IDF says they're targeting a command centre for the Jenin Brigade, "a place where armed terrorists would gather before and after terrorist activities,” the IDF said, adding that the camp was a “site for weapons and explosives” and “hub for coordination and communication among the terrorists," in an effort to break the "safe haven" mentality of the area for terrorists.
They say they told the Palestinian Authoroty and Jordan they were going to do this in advance.
They say "Some 50 shooting attacks against Israelis have emanated from Jenin."
My best guess as to why it doesn't lead to immediate sanctions and isolation is because some governments think the above is true.
Don't riot - the destruction of property has a very serious cost that the rioting society itself will have to bear once all is said and done (whether we get the change we want or not) and it means that efforts and money will have to be put into simply rebuilding rather than progressing. Do mass strikes instead; it hurts them much more, the public is much more likely to be on our side, and the pressure to give in in order to restart the economy will be much greater.
