(Whoa! I really just meant to raise the questions, especially in the case of justification for recent US military conflicts. I'm not advocating for anything!)
Each of this items, alone, would justify many countries in the world to suddenly attack US.
Better not confuse the concepts of attack and defense.
Each of these notions are but rationales used to start a fight, not defend against one.
Once in a while you have a case where it makes sense, but very seldomly.
Most of the time you are much better at defending against uncertainty and economic hardship by putting some money assied rather then building a bunch of tanks.
