Another nice nostalgic mischaracterization of history.
First, with respect to War Crimes, the UN and most international human rights organizations have a consensus that Israel is guilty of War Crimes and Genocide. However, the most powerful European nations, and the U.S., by virtue of their weaponry, and their economic and political power, get the de facto ultimate say. And they never call it a war crime when its not in their interests.
Second, with respect to protest, totalitarian states never allow any protests. Democracies do, but only to the extent that they don't threaten profits, and the power of the ruling class. As soon as they seem to be gaining mass support, threatening profits, making things uncomfortable for the bosses and politicians, they get shut down, often violently. This was true in the 1960s, 1980s, 1990s and today.
