The Real 2) Germany invades neighboring country, after invading a different earlier and promising to both Britain and France in person that "we're done. that was all we want". THIS is unacceptable. Not only are they steadily taking other land, they're lying straight to your face and taking some more after that. Unacceptable under any circumstances.
I'm not sure thats clearly followable.
I believe Nationalism was a huge ideology in this era. You have to realize that the Purssian Empire/Second Reich was a time of national swell for the Germans, they felt like they were the SH**T. The loss of WWI was nothing of a hard blow, they along with the international community saw that the 'document' based on them was a pure joke and nobody was going to follow it. With Hitlers (Rather unlawful) but genius plan to rise the ranks and patch Germany up was unbelievable, he was smart enough to get Germany back to its running ranks. Eventually, the school brainwashing plus the propaganda was a normal thing in Germany.
The end result is, German Pride is almost when you hear the Russian songs talking about 'Mother Russia'. The point is -- you can't screw with them.
German nationalism continuously boomed, and the Nazi regime was basically an outpouring of it. Jews had long been seen as an 'un assimilation' factor in nationalistic make the countries no empires Europe!
The international regard for the treaty that German is to pay back who knows how many 100 Billion's and not do this and that and never have an army for such a large and rather mighty country was outright bogus -- Germany lost land AFTER WWI, because for a moment, they really couldn't do anything.
Their invasion of the Rhineland, In my opinion, is just a bit justified. It used to be Prussian land, Germany accepted those it conquered, and it was - well, they're river. Its almost like someone snagging the Mississippi [even though its like right in the middle and all that, I know]. But the point is, if it were America, we'd snag it back.
The later acquisitions of Poland and Austria (even though Austria was more like a parade...), many called the invasion of Poland the start of WWII -- it clearly didn't look like it, but whatever. Then again, Hitler started attacking a year later. Was there really much to be done? Even to add to that, nobody knew how strong Germany really was. Not to call the world full of pussycats but... They had WWI just a bit ago, and just about everybody knew that during that time fighting a German is like seeing a bear on the street. Your likely to run :S
So I'm not sure that the treaty itself is valuable support for it not being a big war.
