It’s also being perpetrated by those that hold power in the status quo of the world stage, rather than a response to policy. While it was a civilian target, it was at least a civilian target in an actively militarily aggressive country pushing an agenda in the region. Palestine may have guerillas engaged in attacks, but as a country they’re being held down and stomped on rather than out there being an international bully.
It’s worse than 9/11, even if you don’t compare the numbers.
It’s like if Germany started the Holocaust openly and the world was just like okay whatever. Except there aren’t any big Western powers to come to the rescue anymore, because they’re footing the bill and literally providing the gas.
