At the risk of sounding like an Isolationist... that is the difference between the US in 1940 and post-1945... we went from being a Constitutional-Republic to an imperial power (a commercial-imperial power). Empires must fight small brushfire wars as the price of maintaining their position.
Look it how many wars Britain fought around the Globe between 1776 and 1914. Many times their troops got their clocks cleaned in Round One, before they got their act together for Payback. Sounds familiar, right?
If Congress debated every Banana-War the Public would quickly learn the scam. Mostly the everyday voter likes the lifestyle that comes from being top-dog. Those days are coming to an end, so we need to decide if we are returning to the Constitutional-Repblic or something else...
Yes, absolutely. Empires also rot from within by allowing the “riff-raff” in the countries they occupy to come into the home country. This also sounds familiar.
