Because you seem to want to talk about this in good faith let me be clear, at some point this argument expanded to cover general American Isolationism, to which some of my comments are pointed. Some comments may have crossed both subjects at times, though I dont see this as a huge problem because I believe them to be closely linked.It took many years for Japan and Germany to even begin returning dividends, so to speak.
The rest of Europe, well, that's a different scenario to begin with, as they weren't our enemies in war. Well, France sort of, given the Vichy, but that ship long sailed. Europe makes for a poor and rather parasitic ally, I don't disagree, but letting the Nazis or the Soviets conquer it all and entrench themselves would not have been in our best interest either. That's fundamentally why we put up with their behavior, when push comes to shove.
Whether or not the Soviets or Nazis would have been able to sustain themselves without choking to death on their own fuming, sputtering war machines without our involvement being neither here nor there, I understand that the idea of playing world policeman and setting people back on their feet, dusting them off, and trying to help them back towards the light may have been a decent one, but in practice it has proved disastrous and unsustainable. Japan we virtually conquered anyway, replacing their government, a great deal of their culture, and filling their country with our military and business on a scale very much unlike our other "reconstruction" efforts, contemporary or later, with again the exception of SK.
It was not wrong of us to try, it was wrong of us to not stop once we saw where things were going.
Providing trillions of dollars worth of endless help to traitors who despise us (europe) or dumping endless resources into territories we've subjugated but aren't going to claim is self defeating in the extreme.
As it stands, hitting and leaving does no more damage than our current policy of "hit and stick around for ten years getting shot at while we attempt to build the country back up exactly as fast as it collapses, then give up and leave", but accomplishes the same thing "whatever we were pissed about has been bombed into the stone age" with fewer casualties on both sides and a vastly smaller cost.
