Before Hitler invaded Poland, he took a piece of it with Danzig. He annexed Austria, he took a piece of Checkoslovakia arguing that it should be german because the sudet germans lived there.

Seems familliar to what is going on with Ukraine?

Neither Austria nor Czechoslovakia had seen their government shattered by nationalist and ethnocentric coups. This is closer to the Mexican American War...
