Actually (and you'll never hear me credit Moloch for anything again), the way the US handled the Taliban is likely to almost entirely prevent any kind of unified attack against the US from the Middle East, or much of anywhere else. Religion isn't the real issue, it's politics transmuted into religion- we, the "Nation under God", are at odds with all nations ostensibly under Allah, because we both have aggressively expansionist, intolerant doctrines and the world isn't big enough for two jingoistic imperialists any more. When the attack on the WTC happened (never mind the assault on the Pentagon; any attack on that murderous device of destruction is justified), everyone was holding their breath for the US to get redneck on the Taliban, Hussein, and anyone who happened to be standing in the wrong hemisphere. When Bush of all people launched a small, effective attack that wrapped up everything somewhat effectively and installed a benevolent puppet government rather than our usual kind, everyone was so shocked the US came out looking like the good guy on practically all sides. Everyone expected Vietnam mark II. Instead, we got a quick, clean takeover with hardly any civilian casualties, which took the wind out of much of the anti-US rhetoric for a while.
Of coure, we're still bastardly towards most Middle Eastern and African nations (read: oil tyrranies, like in Nigeria, embargoes, etc.), so it won't be long 'till everything's back to normal.
