I believe it's worse not because we invaded but because we rebuilt afterwards and turned it back over to the people who aren't smart enough or were to weak to hold onto the freedoms they were provided. Any nation who allows terrorism to grow in their borders should be held accountable in every way for what those organizations do. If they don't stand up to the extremist in their countries then it will be up to the rest of the world to do it for them but I just don't see that happening in the future. Maybe if the middle east were in the stone age it would be quite a while before terrorist could leave their borders.
