>Except that what you said essentially agreed with me, you just worded it in a way to attempt to justify it.

No, it's opposite.
Your public school teacher:
>in 1938 Hitler promised extra hard to not invade Czechoslovakia and then he did, and thus everyone realized he was mean and had to be stopped!
Reality:
The Munich agreement was signed September 30, 1938. Poland then immediately, on the same day, demanded large chunks of territory that the Czechs had conquered in the 1920 Czech-Polish war, and then invaded October 1, 1938. Hungary then invaded October 5, 1938. Poland began a November, 1938 campaign in Slovakia, invading and annexing territories. This was all hammered out in the Vienna Award on November 2, 1938, an international conference which awarded big chunks of the country to Poland, Hungary, and Romania but not Germany.

Czechoslovakia had thus been invaded by 3 countries that weren't Germany.
Hungary then began making noises about annexing ALL of Slovakia, which until 1919 had been part of the Austro-Hungarian Empire. On March 14, 1939, nearly 6 months after Munich and 4 months after Vienna, Slovakia declared independence and requested German protection, which the Germans agreed to. There wasn't even resistance to the Germans as they walked through

The Germans actually did their best to keep Czechoslovakia alive after Munich, but by March 1939 it did not exist as a country and all of its other neighbors had been openly carving it up ever since Prague was revealed to be toothless. You have to be careful when you're reading the history of a runup to a war, because the commonly accepted narrative is actually the winner's justification for getting into it. If it weren't for the internet textbooks would talk about Saddam's nuclear program.
