What led to the beginning of world war ii in europe, and germany’s early successes

The beginning of WWII happened for a lot of reasons, and a lot of it can be pinned on the league of nations and Great Britain. See, the official start of WWII is the invasion of Poland. But Hitler, in his silly ways, had already invaded at least one country before that. Nothing happened except for a little warning from G.B and the l.o.n. Another reason for the start of WWII is alliances. Just like WWI, everybody was on a side and ready to fight like the preppies and greasers. Poland gets invaded (like your moving on a greaser's gal) and now you got a full blown conflict going on, and you know someone is gonna get shanked. Why did Germany do so well in the beginning you ask, hmmm? Let me tell ya, it was blitzkrieg. Germany moved fast into Poland. In and out, like a sketchy gas station. Get what you want and go. Germany took over and split the nation and then went to Belgium. Deja vu, am I right. All of a sudden, faster that you can say croissant, Germany is marching into France like they own the place. That is why Germany did so good early on. They were fast, and they were capable. They had brains at the head of the organization, at least until he blew 'em out with a pistol.
