Good Wall Street Journal Republicans take Larry Kudlow’s investment advice seriously. Will they listen to him on Afghanistan?

With the killing of Osama, is the Afghan mission complete? The original post-9/11 goal was to kill bin Laden and wipe out al-Qaida. Now that we’ve killed bin Laden and dismantled so much of al-Qaida, do we really need to trudge through an even longer war in Afghanistan? …

I am no military or foreign-policy expert. But I do know the cost of supporting a corrupt regime like Hamid Karzai’s in terms of blood and treasure. The cost is steep. I speak here as a hawk, not a dove. …

Thus far, nearly 1,600 U.S. troops have been killed in action in Afghanistan. To me, this is the most tragic part. Of course, I wholeheartedly support our troops. But is this blood really necessary? Are the projected future costs really necessary?

Again, I ask myself: All this to support Karzai? Isn’t this the sort of nation-building that the late William F. Buckley Jr. opposed? Are American national-security interests really tied up in Afghanistan? Is now not the time to contemplate a much more rapid troop withdrawal from Afghanistan?
