Did Russia help Germany start the World War 2?

In a sense, yes.

World War 2 was going to happen whether Russia (the USSR at the time) helped or not, but they did join up with Germany to help fight.

Stalin was very communist, and just wanted more power. Hitler promised him more land and power if he helped them.

Though, in the end, Russia switched sides when Hitler attempted to invade the USSR (but he failed, which ended up resulting in Stalin switching sides and helping end WW2).
