That’s because they believe that Hamas’s attack on Oct 7 was in retaliation for Israel’s prior actions while Israel is using Oct 7 to retaliate against all of Palestine. Palestinians are going to support the side that is not bombing them and that they believe is standing up to the persecution they’ve experienced up until and including now.
It’s crazy to me that these countries cut funding, even after they fired those people. UNRWA is providing much needed help, from what I’ve heard of the reporting so far, and this disrupts those efforts a lot.
