> not a single country will accept a soverein Palestenian state, because they're ruled by terrorists.
You yourself say that Palestinians can live completely peacefully, why can't they have a sovereign state with a better government? I hope that after years of Israeli government / Netanyahu supporting Hamas [1], they will change the strategy.
Murder/attempted murder of adversary citizens in neutral territory is just one of a legion of examples of behavior the West constantly criticizes Russia for, by the way.
The Russian government kills unarmed civilians outside of Russia. Usually Russians, but not always. The Israeli government also kills unarmed civilians outside of Israel. So yes, in the category of "nation states that covertly murder people globally with negligible consequences", both are present. Hell even India is in that group lately...
