You don't think those odds are going up?
After the Paris attack, San Bernardino and the Russian airliner, all in a months time, doesn't that give you reason to be concerned? France just foiled an attack in the Orleans region three days ago.
I don't understand this "bury your head in the sand attitude". We need to be doing "something" other than what we have been doing. In the mean time, our "adversaries" are gaining strength. There's no need for fear, just action.
