Seriously, what Israel is doing today is no different from what the Nazis did before and at the beginning of World War II, extreme nationalism, illegal expansion, annexation of foreign territory claiming it historically belongs to them, propaganda using the latest technology, terrorizing neighbors, military at the center of society.
However, the problem is that these extremist influences are not a new occurrence in Zionism but have been a part of it since the beginning of the political movement. The question of how to deal with the fact there was basically no habitable place on earth left uninhabited to found a state in, was answered very differently by different parts of the movement.
