Chamberlain returned to Britain after Munich to streets lined with cheering Brits.
It was Hitler who messed up by grabbing all of Czechoslovakia.
Sometimes I think we messed up, we shoulda invaded Russia in 1939 when they helped start ww2 by dividing up Poland. We could have ended up with vast chunks of Siberia.
hitler didn't grab all of Czechoslovakia in 1938. He split off Slovakia and he made Czechia a vassal state
But after that he invaded Poland
Appeasing Putin with Crimea didn't work - he will constantly want more.
