It is sooooooo important for the US the Irak and Afghanistan wars, strategically, geopolitically, military, they are sooo important for the US, than 10 years later they are still there, they didnt leave! Saddam is dead, Osama is dead there were no weapons.... but they are still there.
It is important to me the way the US sold these wars to its citizens. They needed some consensus you know? they needed something beyond politics, something big, some reason that did not require any explanation. The war on terror must have been something emotional to every american citizen, not something reasonable, they appealed to the emotions, not to the reason, thats why these wars are out of discussions, or at least they were in the beginning. Little to no one opposed to the wars in the beginning, thats because the propaganda, thats because how the government sold the wars to its citizens. Today they are more questionable, but at that time, they did arrive to that consensus, to that homogenious opinion that they must go to war.
And it had to be like hollywood, with big explosions in everyones face. It was sooooo used the 9/11 after. Like for 10 years, it was used to justify wars, budget to the defense department. patriot act, more and more power to the military industrial complex, the same that killed Kennedy, the same that governs the US, and the world, since the end of WWII.
