The Dubai hit, if it were Mossad, was not an act of self defense. it was done to perpetuate, and eliminate opposition to, the Israeli 42-year illegal occupation of another peoples territory. That occupation is in violation of international law. Israelis kill resistors to oppress those who rebel against that violation of international law. International law works just fine to take down international terrorists. In a recent 4-day period, Saudi Arabia killed 15 Al Qaeda members. They have over 200 in prison. Of the 28, or so top Al Qaeda members on 9/11, only 3 remain alive or not incarcerated. The US and the Pakistanis just captured 12 top members of the Taliban. Hamas is not an international terrorist organization. Israel is not in the fight against international terrorism, and has not faced mass terror. Re EU, all countries hand-wring when their sovereignty has been violated. And there will be consequences for the violator. Nothing you note was lost on anybody serious.
