Same thing as during the Gulf War. My boss was at Khe Sanh. He predicted that the Republican Guard would crack as soon as the ground war started, due to the B-52 strikes. He also predicted that the Taliban front lines would crack for the same reason.
The difference between him and Molly Ivins/various pundits/ex-generals? He spent a couple months near B-52 strikes, so he knows firsthand how terrifying the B-52 strikes could be even when they were on his side. Imagine what it's like to spend weeks as the *target* of B-52 strikes. Always talk to those who actually experienced what we're doing, not those who are only guessing.
