Well times haven't been looking very good lately, don't know how bad it was over there but things could get real bad here. Also while they might of been ticked about how they were treated after the war, many here are ticked about a certain war that we are in. While I certainly wouldn't compare Obama to Hitler, but it is possible for what is planned under Obama to eventually morph into something far worse in the future.
After WWI, Germany was forced to pay reparations to the Allied countries, which strained the German economy. The Versailles Treaty also took German land--some of it the most valuable industrial land--and gave it to other countries.
Germany needed to revalue its currency to cover the cost of the reparations, and also the tariffs other countries put in place to block German exports. In 1920 the exchange rate was 40 Marks to 1 US Dollar. By 1923 the rate was $4.2 trillion marks to $1 US. It literally took bushels of Marks to buy a loaf of bread.
This was all happening in advance of the Great Depression. When the world financial markets were hit in 1929, Germany took it even worse. In addition to an almost worthless currency, the country had an unemployment rate that ran as high as 33%.
People may be ticked off here about the war in Iraq, but we're not giving up the Midwest to another country because of it, or being forced to pay another country a huge amount of our GDP for reparations.
We'd have to be in much more dire straits to enable the rise of a Nazi-like regime.
