What will be the biggest question of this century?
Still the big unanswered question of the last century is, how could evil take over Germany. Most people can't answer that question if asked, because nobody was ever explained in detail how they took over Germany.
So what you have to look out for is when a politician start to tell you these details, because when they start to tell you these details they start to warn the people, and because of this warning people start to realize that what is currently happening in politics is the same, and because of that people are going to trust this politician and vote in mass on this politician (because he warned for a repeat)
And even if they don't warn there still could be a repeat, because this is were the current political situation (in Europe) is heading for. In e.g. Greece and France you see political splits. But in Russia you already see the situation going towards absolute number of votes. One way or the other they will reach that amount of absolute votes/power, and then they have you checked. Then they can push forward there agenda, because voting means that you submit to a politician (you see them as your leader), and of a majority of the people did this, they all will obey and listen what 'their' leader will tell them (and will follow orders, most will?)
