Regarding Sens. John McCain (R-Ariz.) and Lindsey O. Graham’s (R-S.C.) March 15 op-ed, “We need more forces in Afghanistan”:

None of the terrorists who took part in the Sept. 11, 2001, attacks was from Afghanistan. If you posit a global terrorist network, no single country is essential to its existence, so denial of a sanctuary in Afghanistan will only cause terrorists to move to other locations. And they have choices.

If a nation cannot win a war after a decade and a half, perhaps it’s time to reconsider its goals. That doesn’t mean the war was lost, but rather that leaders are focusing on other priorities. We got out of Vietnam literally overnight, and today that country is at peace. Many of those living in Vietnam today don’t remember the war. When I was in Vietnam in 1964, no one there could remember peace. The British and Russians tried and failed to control Afghanistan. It was once important because of trade routes, but it has little strategic importance in the modern world.

The United States can continue to support its interests in Afghanistan with foreign aid through the State Department, but please, no armies.
