We have lost our nerve, and so has the Brits. The American people do not understand war and lack the guts to see a war through, unless it is a quickie with no or low losses such as the invasion of Granada. Our enemies are emboldened while we worry about offending the sensibilities of Muslims or, god forbid, cause a few civilian casualties in the course of military action. I served in our Army for over twenty years, and while our military is the best in the world, we lack the resolve and political will to use our power to further American interests. Probably not in my lifetime (because I am getting old) but likely in my children's lifetime we will see America fall from our leadership of the world, and bit by bit suffer the losses as others impose their will upon us. Even 9/11 did not really awaken our people, and I am not sure if we lose a city to a nuclear attack if Americans will rise up and fight or just to talk our way into some temporary truce with our enemies. Maybe if the Brits still were led by a Margaret Thatcher we would see decisive action, but I doubt it will happen under Tony Blair or any of his successors.
