And basically guaranteeing we would have no other choice but to resort to nuclear weapons to defend ourselves if we were required to fight off an enemy attacking from two fronts. Yeah, this is REAL smart thinking...
Sorry, I keep forgetting we should have just let Hitler run roughshod over Europe, Great Britain, and the Soviet Union, it wasn't 'our' fight anyway. What was I thinking, Hitler would have never posed a threat to the United States even though he declared war on us... Oh, the Japanese attacked Pearl Harbor.
When have we faced two possible future adversaries like a China and Russia who if so inclined could attack the continental United States in a matter of minutes? Your giant island isn't so giant or isolated in today's world. BTW, when has an economic superpower never become a military superpower?
So what your saying is that we don't want to be forced into counting on our nuclear weapons, we could be attacked very quickly with nuclear weapons, and we need a huge conventional military to respond with since we shouldn't rely on nuclear weapons?
