Another thing to keep in mind that attacks in non-Western states predate those on the US - and are a harbinger of things to come; the attacks on the US embassies in Africa; the USS Cole; etc.
The situation in Pakistan is highly unstable, and terror in Pakistan has spilled over into India. That’s got serious international ramifications on multiple levels. The Somali pirates are another problem - Somalia in general actually. Failed states are safe havens and terror incubators.
