Where do you come by the assertion that "In a Democratic Society The People traditionally & historically are Pacifist, why aren't we?"
There have not been any countries in history to compare to the USA. The United States Constitution redefined democracy.
What the USA has done over the past 250 years has not been perfect but it still is the best form of government in human history. Let's hope that it continues to get better.
Back to your statement - if the US is not attacked then the US will not start a war. Look what it took to get the US into WWII and WWI. Yes, I know the US is not perfect - the Iraq war proved that.
