American's wars

Personally I have never been affected by the war in Iraq. I am not American so I have never deeply thought about the consequences it has. However, I want to say a thing about something about USA and the wars they have always fought.
First of all, besides the civil war, Americans have never felt the consequences of a war in their own country. They have always fought “they’re” wars in other countries territories. They have always been in a force position, showing their strength to the whole world. The first time American territory got attacked was 9/11/2001, and everybody saw what happened. That was the first time Americans felt fear, got scared. That is the most normal thing in the world (to get scared), but still, what happened is not comparable to what happened (and still happens) to people in Afghanistan and Iraq. Everybody in those countries, live in the fear that a bomb might drop in their house or a kamikaze might blow up the building they work in. Personally I do not remember those things happening (especially in Iraq) before the American Government decided fight the presumable terrorists in Iraq’s territory. As I recall, the motive for the attack was that Iraq was in posses of technologies that could produce biological-mass destruction weapons and certainly, the target was USA. That fact was never proved! The scientists sent there to investigate never find anything close to a biological weapon. However, USA continued their mission of fighting terrorism in the world and attacked Iraq. I don’t want to go deep into the real reasons (I believe) that led to that war but, probably they felt that a second 9/11 might have happened so they decided to go and invade Iraq.
However, there is one thing that comes up to my mind when I think about USA and its wars, and the Iraq’s war enforces my idea: They always fight they’re wars away from home because that is more comfortable, because that’s what they are used to do! Yeah…right! Who wouldn’t want to do that if they had the chance to!
