Ministers can have both positive and negative effects on the country. Some ministers may be hard, or impossible to get rid of, some may cost an upkeep of political points every week to work for you, and some may even help your political power grow faster. Your government is filled by you by spending political power. Well at least short term, and this let him dictate policy without being questioned. I have a feeling there was a generous serving of good luck there, but nevertheless the effect was that his political power grew - he had been right when everyone else argued caution. Hitler gambled right that none of the League of Nations members felt strong enough to flex their muscles and stop him. There were groups convinced that he would bring ruin to Germany and were about to stage a coup vs Hitler as he went from breaking treaties by putting German military presence in the Rhineland and onwards to annexations of Austria and Czechoslovakia. We modeled this mechanic around how Hitler historically secured his grip on Germany and started WWII, the idea being that you need to pull off some stuff to build confidence in your ruling powers.
