Starting in 2011, we are prepared to freeze government spending for three years. Spending related to our national security, Medicare, Medicaid and Social Security will not be affected. But all other discretionary government programs will. Like any cash-strapped family, we will work within a budget to invest in what we need and sacrifice what we don't. And if I have to enforce this discipline by veto, I will.

We will continue to go through the budget line by line to eliminate programs that we can't afford and don't work. We've already identified $20 billion in savings for next year. To help working families, we will extend our middle-class tax cuts. But at a time of record deficits, we will not continue tax cuts for oil companies, investment fund managers and those making over $250,000 a year. We just can't afford it.

Now, even after paying for what we spent on my watch, we will still face the massive deficit we had when I took office. More importantly, the cost of Medicare, Medicaid and Social Security will continue to skyrocket. That's why I've called for a bipartisan fiscal commission, modeled on a proposal by Republican Judd Gregg and Democrat Kent Conrad. This can't be one of those Washington gimmicks that lets us pretend we solved a problem. The commission will have to provide a specific set of solutions by a certain deadline. Yesterday, the Senate blocked a bill that would have created this commission. So I will issue an executive order that will allow us to go forward, because I refuse to pass this problem on to another generation of Americans. And when the vote comes tomorrow, the Senate should restore the pay-as-you-go law that was a big reason why we had record surpluses in the 1990s.

I know that some in my own party will argue that we cannot address the deficit or freeze government spending when so many are still hurting. I agree, which is why this freeze will not take effect until next year, when the economy is stronger. But understand — if we do not take meaningful steps to rein in our debt, it could damage our markets, increase the cost of borrowing and jeopardize our recovery — all of which could have an even worse effect on our job growth and family incomes.

From some on the right, I expect we'll hear a different argument — that if we just make fewer investments in our people, extend tax cuts for wealthier Americans, eliminate more regulations and maintain the status quo on health care, our deficits will go away. The problem is, that's what we did for eight years. That's what helped lead us into this crisis. It's what helped lead to these deficits. And we cannot do it again.

Rather than fight the same tired battles that have dominated Washington for decades, it's time to try something new. Let's invest in our people without leaving them a mountain of debt. Let's meet our responsibility to the citizens who sent us here. Let's try common sense.

To do that, we have to recognize that we face more than a deficit of dollars right now. We face a deficit of trust — deep and corrosive doubts about how Washington works that have been growing for years. To close that credibility gap we must take action on both ends of Pennsylvania Avenue to end the outsized influence of lobbyists; to do our work openly and to give our people the government they deserve.

That's what I came to Washington to do. That's why — for the first time in history — my administration posts our White House visitors online. And that's why we've excluded lobbyists from policymaking jobs or seats on federal boards and commissions.

But we can't stop there. It's time to require lobbyists to disclose each contact they make on behalf of a client with my administration or Congress. And it's time to put strict limits on the contributions that lobbyists give to candidates for federal office. Last week, the Supreme Court reversed a century of law to open the floodgates for special interests — including foreign corporations — to spend without limit in our elections. Well, I don't think American elections should be bankrolled by America's most powerful interests, or worse, by foreign entities. They should be decided by the American people, and that's why I'm urging Democrats and Republicans to pass a bill that helps to right this wrong.

I'm also calling on Congress to continue down the path of earmark reform. You have trimmed some of this spending and embraced some meaningful change. But restoring the public trust demands more. For example, some members of Congress post some earmark requests online. Tonight, I'm calling on Congress to publish all earmark requests on a single Web site before there's a vote, so that the American people can see how their money is being spent.

Of course, none of these reforms will even happen if we don't also reform how we work with one another.

Now, I am not naive. I never thought the mere fact of my election would usher in peace, harmony and some post-partisan era. I knew that both parties have fed divisions that are deeply entrenched. And on some issues, there are simply philosophical differences that will always cause us to part ways. These disagreements, about the role of government in our lives, about our national priorities and our national security, have been taking place for over 200 years. They are the very essence of our democracy.

But what frustrates the American people is a Washington where every day is election day. We cannot wage a perpetual campaign where the only goal is to see who can get the most embarrassing headlines about their opponent — a belief that if you lose, I win. Neither party should delay or obstruct every single bill just because they can. The confirmation of well-qualified public servants should not be held hostage to the pet projects or grudges of a few individual senators. Washington may think that saying anything about the other side, no matter how false, is just part of the game. But it is precisely such politics that has stopped either party from helping the American people. Worse yet, it is sowing further division among our citizens and further distrust in our government.

So no, I will not give up on changing the tone of our politics. I know it's an election year. And after last week, it is clear that campaign fever has come even earlier than usual. But we still need to govern. To Democrats, I would remind you that we still have the largest majority in decades, and the people expect us to solve some problems, not run for the hills. And if the Republican leadership is going to insist that 60 votes in the Senate are required to do any business at all in this town, then the responsibility to govern is now yours as well. Just saying no to everything may be good short-term politics, but it's not leadership. We were sent here to serve our citizens, not our ambitions. So let's show the American people that we can do it together. This week, I'll be addressing a meeting of the House Republicans. And I would like to begin monthly meetings with both the Democratic and Republican leadership. I know you can't wait.

Throughout our history, no issue has united this country more than our security. Sadly, some of the unity we felt after 9/11 has dissipated. We can argue all we want about who's to blame for this, but I am not interested in relitigating the past. I know that all of us love this country. All of us are committed to its defense. So let's put aside the schoolyard taunts about who is tough. Let's reject the false choice between protecting our people and upholding our values. Let's leave behind the fear and division and do what it takes to defend our nation and forge a more hopeful future — for America and the world.

That is the work we began last year. Since the day I took office, we have renewed our focus on the terrorists who threaten our nation. We have made substantial investments in our homeland security and disrupted plots that threatened to take American lives. We are filling unacceptable gaps revealed by the failed Christmas attack, with better airline security and swifter action on our intelligence. We have prohibited torture and strengthened partnerships from the Pacific to South Asia to the Arabian Peninsula. And in the last year, hundreds of al-Qaida's fighters and affiliates, including many senior leaders, have been captured or killed — far more than in 2008.

In Afghanistan, we are increasing our troops and training Afghan Security Forces so they can begin to take the lead in July of 2011 and our troops can begin to come home. We will reward good governance, reduce corruption and support the rights of all Afghans — men and women alike. We are joined by allies and partners who have increased their own commitment, and who will come together tomorrow in London to reaffirm our common purpose. There will be difficult days ahead. But I am confident we will succeed.

As we take the fight to al-Qaida, we are responsibly leaving Iraq to its people. As a candidate, I promised that I would end this war, and that is what I am doing as president. We will have all of our combat troops out of Iraq by the end of this August. We will support the Iraqi government as they hold elections, and continue to partner with the Iraqi people to promote regional peace and prosperity. But make no mistake: This war is ending, and all of our troops are coming home.

Tonight, all of our men and women in uniform — in Iraq, Afghanistan and around the world — must know that they have our respect, our gratitude and our full support. And just as they must have the resources they need in war, we all have a responsibility to support them when they come home. That is why we made the largest increase in investments for veterans in decades. That is why we are building a 21st century VA. And that is why Michelle has joined with Jill Biden to forge a national commitment to support military families.

Even as we prosecute two wars, we are also confronting perhaps the greatest danger to the American people — the threat of nuclear weapons. I have embraced the vision of John F. Kennedy and Ronald Reagan through a strategy that reverses the spread of these weapons and seeks a world without them. To reduce our stockpiles and launchers, while ensuring our deterrent, the United States and Russia are completing negotiations on the farthest-reaching arms control treaty in nearly two decades. And at April's nuclear security summit, we will bring 44 nations together behind a clear goal: securing all vulnerable nuclear materials around the world in four years, so that they never fall into the hands of terrorists.

These diplomatic efforts have also strengthened our hand in dealing with those nations that insist on violating international agreements in pursuit of these weapons. That is why North Korea now faces increased isolation and stronger sanctions — sanctions that are being vigorously enforced. That is why the international community is more united, and the Islamic Republic of Iran is more isolated. And as Iran's leaders continue to ignore their obligations, there should be no doubt: They, too, will face growing consequences.
