I see an increasing number of politicians taking the position: "I supported Israel's government's actions when they first attacked, given the goals of destroying Hamas' leadership and freeing hostages, but now that it has turned into a brutal siege with mass civilian casualties on a horrific scale, I'm strongly against their actions." E.g. Macron, Angus King, and many people I know personally. And I think we need to…
The situation hasn't changed. The data is the same going back years. It's healthy to be cautious of people who join a movement under false pretenses like that.
If they learned a new perspective, that's great! I just wish it didn't have to come to personally witnessing such brutality to gain a new perspective...
