Both are none of the American business.

As a serious note, what has happened on 7th of october was most definitely known beforehand by Israeli government and was entirely under their control, if not staged by them in the first place. Unless you don't know, the gaza strip is (unlawfully) blockaded from all sides, including the sea, with rigorous checkpoint inspections to make sure that absolutely nothing goes in or out without Israeli knowledge. There is a huge fucking wall on the border that'd make Trump jealous, patrolled 24/7 by a whole battalion of armed forces and equipped with the most state-of-the art surveillance equipment, capable of tracking every single bird flying over Gaza. The only way a bunch of bozos on bulldozers could even approach it undetected is if Israeli intentionally removed security and disabled surveillance over some parts of the wall.
