Funny how a guy named Chamberlain agreed to "just a nibble" to make a dictator happy, and the next thing you know the world was at war. For whatever reason, a lot of people try really hard to forget history. The sad part is that, unlike then, there are missiles and bombers that can cross the oceans, subs that can park off the coast and launch shorter range missiles, and people still think we can be isolationists while being a major power. If Russia and China pick off other countries one at a time and become stronger because we chose not to help out, it seems pretty obvious what the end game is.
Another guy named Martin Niemöller in hindsight made quite a statement when he penned
"First they came for the socialists, and I did not speak out—because I was not a socialist.
Then they came for the trade unionists, and I did not speak out—because I was not a trade unionist.
Then they came for the Jews, and I did not speak out—because I was not a Jew.
Then they came for me—and there was no one left to speak for me."
