From photos, indiginous construction is largely brick and stone.

Stone doesn't burn at anything near attainable temperatures.

Note too: Dreseden was firebombed. For a US perspective, see Vonnegut's Slaughterhouse Five.

My read is that the air assaults are paving the way for ground war. We've knocked out enough defenses to fly day raids now. The NA report having severed the Taliban's northerthern forces' supply route, and Taliban airborne resupply is preempted by US air superiority.

I expect land actions to commence within the week.
