The question of whether President Obama should send more troops to Afghanistan misses the point.

What Obama really needs to do is: Invent a time machine, go back to the 2008 presidential campaign and not say, over and over and over again, that Afghanistan was a "war of necessity" while the war in Iraq was a "war of choice." (Oh, and as long as you're back there, ditch Van Jones, Valerie Jarrett and that gay "school safety" czar.)

The most important part of warfare is picking your battlefield, and President Bush picked Iraq for a reason.

Neither Iraq nor Afghanistan attacked us on 9/11 -- or the dozen other times American embassies, barracks and buildings came under jihadist onslaught since Jimmy Carter presided over "regime change" in Iran in 1979. Both countries -- and others -- gave succor to terrorists who had attacked the U.S. repeatedly, and would do so again.

As liberals endlessly reminded us during the three weeks of war in Afghanistan before the U.S. military swept into Kabul, Afghanistan has all the makings of a military disaster. It is mountainous, cave-pocked, tribal, has no resources worth fighting for and a populace that makes Khalid Sheikh Mohammed look like Alistair Cooke.
