I genuinely don’t believe the Biden admin’s stance on this issue is due to votes or donations. I think Biden believes that Israel is waging a just war, a defensive war, on terrorism, and that even if America doesn’t agree with their tactics, we are duty bound to support them.
If we follow a trend line of all American Presidents going back 50+ years, which administration, Democrat or Republican, was unwilling to indiscriminately kill thousands of Arab Muslims? America simply does not value the lives of Arab Muslims, and won’t hesitate as a nation to kill them or support other nations killing them. Biden is not unique in this regard.
