And of course it follows (rationally) that Israel should cease its violation of international law, just like all other violators should. And if they continue to break the law (as Israel has for many decades) the rational response is to encourage the nations in question to respect international law. This is done all the time, both by nations and by smaller groups of people, and contrary to your belief not solely directed at Israel. Anyway if Israel wants to call itself a democracy it is going to be held to the standards of other democracies. Israel is included in a sphere of countries that enjoy all kinds of trade, scientific and military relations with each other (benefits that are not shared by most violators of international law). But when Israel acts in a way that does not befit countries in this sphere you should not be surprised if those relations are being questioned. As for this supposed bias: please bring some more facts - especially about your accusation of personal bias on my part.
