Trench warfare is certainly applicable to the situation here as well. We might be lagging behind the US, but polarization is steadily increasing. Nobody seems willing to address the real issues at hand. Instead people are arguing semantics and calling each other nazis, and it's getting increasingly hard to gather a majority for passing a budget, not to mention actually forming a government.

I honestly don't think a handful more political parties will do that much of a difference to combat the current zeitgeist.
