Please don't take this as being mean-spirited but how old are you roughly (I know thats a question your not suppose to ask a woman but...)? I remember those days (like they happened yesterday) when those terrorists rammed those jets into the World Trade Centers, the Pentagon, and the unsuccessful (thank God) Pennsylvania field. Our nation had to respond in some fashion for all those innocent lives taken on that day. And it wasn't out of revenge, it was out of justice. If there was some way to have apprehended those terrorists who organized the attacks, the US should have done so (I have no answers there) but our intelligence on the ground, our military, and our leaders (most of them) said war was inevitable.
But once again with war, we learn it never solves a problem. The days of conquering a land and forcing your values on a people are way over. At the time though, people of America wanted something done for the terroristic acts and most of our leaders responded the only way they knew how. So don't blame then Pres Bush. How does one respond to jets filled with beautiful human beings being slammed into building or the ground at a high speed.
Diplomacy should have happened even further back when we supported the Afgan Rebels against the Soviet Union. All in the name of democracy and capitalism. You could probably take these ills even further back. Its a crazy world we live in. All we can do is pray and follow our God's ways
