Keep on thinking the bombs dropped in Iraq and Afghanistan were smart enough to tell fanatics and spare civilians if it helps. 
Modern culture, today, faces no bigger threat than religious fundamentalism.
For the most part, yes they are smart enough. We also have rules of engagement, which terrorists don't have. We don't decapitate noncombatants. We don't intentionally kill civilians. Another difference between "us" and "them."
Alarmist nonsense dude. The biggest threats American modern culture faces are the expansion of the federal government, debt, and foreign terrorists who want us dead.
