I suppose we should not have fought in WWII or WwII until we were forced to fight without allies or access to the nation's terrain of our enemies. I accept wide latitude for the federal government so spy externally, and to a limited degree internally. I also accept wide latitude for offensive and defensive engagements the world over if they advance a strategy to defeat this nation's enemies before they are capable of invasion or direct attack against us.
Not everyone is so thoughtful. Some wish to turn the Constitution into a suicide pact.
