Focus,
The world is not black and white, it is a million shades of gray.
You wanna know when the "War on Terror" will be over? When we have either found an alternate fuel source or when all the oil in the Persian Gulf is used up. Until then, we have to deal with these people.
You should read a book called Mega-Trends. It talks about how the world is transitioning from an industrial-based to an information-based system. In an industrial-based system, nation-states are very important. In an information-based system, they are not. The idea of strong nationalism is becoming an outdated concept.
Want proof? In the past, our enemy was Germany, Japan or Russia. Today it is a terrorist network made up of citizens of many different countries. They are using mass communications to coordinate and plan. The days of having your enemies defined simply by geography are over.
For example, let's say we invaded Iran. We could take it over geographically, but the real enemy would still exist because the "enemy" is from many different countries. Same thing with Iraq. Instead of invading Iran, maybe we should do away with mass communication.
