They’ll support Israel because the way we do it is another of the many infinite money hacks our MIC has created and entrenched deep into our politics. I really dislike this American trend to racialize the conflict. In virtually every way, Palestinians and Israelis, and Jews in general for that matter, are pretty indistinguishable but for small differences in otherwise very similar ethnic and religious cultures. Jewish culture, even across the diaspora, has been pretty clearly a Levantine originating one forever (not to mention the far deeper similarities between Judaism as a religion and Islam than between either and Christianity).
The actual entry into Afghanistan and overwhelming of local forces was wildly fast? The majority of our time in Afghanistan wasn’t slowly advancing on Kabul. It was failing miserably to build a coherent state sympathetic to US interests amidst a mad dash of privatized MIC interests maximally extracting revenues from the US.
