He was essentially given Austria (during the Anschluss) and Czechoslovakia (which had a strong, modern military and could have stopped Hitler in his tracks had he tried to invade).
He claimed Austria and occupied the Czech. He then invaded Poland with little resistance from the other countries. During the invasion of Poland, Germany could have been invaded and defeated since little was left to defend the country.
Anyways, I think we do agree on quite a bit. I just want a serious debate about whether or not to invade a country, not fashioned as “you’re either for us or against us” or “if you don’t support this war you’re a traitor”
