Couple things: 1) Israel is surrounded by enemies who hate them. Hamas is supported by Iran, who is supported by Russia, one of the world's powers. We can go down the list of the other regional powers if you like: Hezbollah in Lebanon, Syria, and so on. And of course we don't need to recount the centuries' long history of people around the world hating and persecuting Jews. 2) Ukraine, if you want to compare the situations, has come out in strong support of Israel and condemned the attack by Hamas. Russia, on the other hand, has been quiet. It was Hamas who invaded Israeli territory that ignited this round of war. So IMHO the US should be supporting both Ukraine's and Israel's rights to defend themselves - which we are doing.
I believe you have good intentions (as I've always found to be the case), but there are a few key points here that I think require so much more context and others that I strongly disagree with, for multiple reasons. We definitely agree on opposing Hamas' attacks on civilians, however.
We could discuss the Israeli-Palestinian conflict sometime if you would like. I'm just mostly avoiding debates about the subject for now.
