I’m curious, what exactly gives a sense of OP being an Israel supporter? I read the post as good pondering about the reasoning for Israel’s reactions and some good analogy for US readers through the 9/11 attacks and reactions for it.
It’s pretty much required that a nation will either defend themselves or even counterattack heavily if someone attacks them or otherwise they won’t stay independent very long (see Ukraine currently or Europe in 1930-1940s) and understanding that doesn’t make someone automatically a supporter of either side. Now, it’s a good thing to discuss about the size of Israel’s reaction because completely destroying another country over a terrorist attack is not going to end up well either. This is something where the 9/11 comparison works well in my mind.
