Are we the World Police? I know people argue that we are. WHY? Why us? Why not slash all that spending and downsize. Let the world police itself.
I believe the last time we did something like the was in the 1930s during that time Hitler and the Nazi party rose to power in Germany and Imperial Japan rose to power in the pacific. The world did a very poor job of policing it's self and despite our small, poorly trained and equipped military we still ended up in a second world war there have been numerous conflicts since then but there has not been another world war since the U.S. began maintaining a large standing military take from this what you will.
Your history is wrong. We meddled in Europe's affairs in 1917 and ended up causing the humiliation of Germany which laid the groundwork for Nazism.
Actually YOUR history could use a little reality check: Germany was practically beat when we joined the war, and the Allies, mainly France and UK dictated the terms of
armistice. Finally there were a number of factors which "laid the groundwork for Nazism," one of which was the unfavorable terms of the armistice.
Now, back to the present: Much has been written in this thread about the fact that the USA has no credable enemies, i.e. countries that could actually invade the USA.
Maybe this is because we have a very large, effective military?
Could it be half its present size, and still be as effective?
Should we try to find out?
Before answering this last question, realise the military today is not the military of 1935, when armaments and the personnel needed to man them were relatively simple: most farmers could jump off their tractor and drive a tank. Airplanes did not exceed about 450 mph., and "radar" was a novelty. Significantly reducing the size of the military TODAY means it will take DECADES to rearm and reman those weapon systems and logistical support for them.
