Our growing violence

In the past 50 years the USA has fought in more wars than we did in our first 150 years of founding. We went from being an isolationist country that barely had a standing army, to a nation that prides itself on a nation that spends twice as much money per soldier than any other country. We stick our nose into everything, our reasoning: Spread democracy. What I think is the real reason is that we are becoming more and more nervous around other countries. We think that we are always under constant threat of attack and therefore we want to attack the problem before it attacks us. We have become so cocky with our military that we believe that whoever we attack, we will win. And I honestly believe this is a good thing, with out a little swagger we would succumb to pressure and would not be a powerful nation.
