Worse choices have been made than Barack Obama for the Nobel Peace Prize.

There was Woodrow Wilson in 1919, an award that rates as one of history's more grotesque international jokes. Wilson promised to keep us out of war and promptly got us into it, meanwhile laying the ideological and geopolitical foundations for 90 years of war-nationalism, war-liberalism, and war-socialism. To say nothing of saddling us with the terrible idea of world government. Among those who weren't Nazis or communists, Wilson may have done more than any other individual to promote human suffering in the last hundred years.

So yes, there have been worse choices. (Next to Wilson, I'd have to give Al Gore and Yasser Arafat both honorable mentions. We could go on, of course.) But still, Barack Obama? Seriously? I doubt the committee has any idea how badly their choice will be mocked in the United States.

Over here, the prize will be a disappointment to the anti-war left, the anti-war right, and, of course, the pro-war right. The only contingent I can see taking pride in it over here is the establishment left, which hasn't had much time lately for substantive work on peace, but which is always happy to make speeches and receive awards. Sometimes, the American image abroad is just that important.

Rather than piling on in what is sure to be a bipartisan laugh-fest, let's think about what Barack Obama actually could have done for world peace. And weep.

Like Wilson, Obama ran a campaign promising peace and the international rule of law. Politically, peace is a winning message, and the advocates of peace would do well to remember this. Decade after decade, American voters are willing to give peace a chance.

Obama promised to withdraw from Iraq and to close the illegal Guantanamo Bay prison camp. He promised to end the Bush-era detention and rendition policies that have tarnished America's reputation abroad and weakened trust among nations.

Americans embraced those promises, which are fully consistent with the ideals of the Nobel Peace Prize. The prize, recall, is awarded "to the person who shall have done the most or the best work for fraternity between nations, for the abolition or reduction of standing armies and for the holding and promotion of peace congresses." Ending wars, treating prisoners of war humanely, and ensuring international criminal suspects' due process of law are exactly the sorts of things that the peace prize was designed for. They're just what you'd expect a laureate to do.

But once in office, Obama didn't deliver. The promises disappeared, replaced by vigorous defenses of virtually every presidential power that the Bush administration invented for itself, including not only those that subvert domestic civil liberties, but also those that threaten the international rule of law.

And the withdrawal from Iraq? Delayed and partial. The latest word — received just as the peace prize was announced — is that it's "complicated." Sort of like a bad Facebook relationship.

Our other war, in Afghanistan, continues to escalate, even as its strategic goals seem further and further removed. As Cato author Glenn Greenwald notes, U.S. airstrikes in Afghanistan continue to kill and maim the innocent, with very little to show in the way of stabilizing the country or defeating international terrorism. Withdrawal from Afghanistan is both possible and desirable, as my colleagues Malou Innocent and Ted Galen Carpenter argue. Yet our latest Nobel laureate doesn't see peace as an option here either.

How sad. Not to sound bitter or anything, but when does the Cato Institute get a peace prize?
