The failure of the liberal left and frankly the decadent  governments of the West for the last decade is not taking seriously the threats of tyrants and madmen preferring diplomacy over force.  The time to have prevented rouge states like NK and Iran from obtaining nuclear weapons would have been much easier years ago when they didn't actually posses such devices or deliver systems.  These liberals lefties can pat themselves on the back for keeping the peace at the time but in the end we'll be at war with these terrorist governments and as a direct result we'll have to pay with added buckets of blood.
