Debunker has answered question number 1. As for question number 2, an awful lot of people will claim that the Versailles treaty justifies German aggression in WWII. If that is the explanation for Germany's actions from 1939, I can't quite see how it explains the actions of Japan and Italy, both on the winning side at the end of WWI.
Hitler developed a concept of "Lebensraum", "living space", although "killing space" would have been more apt. The existing inhabitants of Poland, Ukraine and Belarus were to be killed, or starved to death (and the English "to starve" is cognate with the German "sterben" - "to die"), to make way for German settlers. That was the primary aim of Hitler's war in the east. The plans still exist of the city that was intended to be built at Auschwitz. Those plans preceded the infamous death camp.
I think Timothy Snyder argues very persuasively in "Bloodlands" (given its subject matter, a pretty harrowing read) that genocide of Jews was always a nazi objective, but started off at the bottom of the check-list of Hitler's aims, when he launched Barbarossa. That's not to deny that mass-murder of Jews took place right from the start, but it became the one "achievement" which nazism could extricate from the eastern front, where the original plans envisaged massive conquests, wholesale colonisation and killing on a scale that would have dwarfed even the Holocaust. As Germany faced defeat, genocide was the only one of Hitler's war aims still accessible.
I recommend Snyder's "Bloodlands".
