That's exactly what Biden said, and I fear that he is right. It hasn't happened yet and I don't actually believe Biden wants it to happen, but he apparently understands history well enough to see that it will repeat itself, yet again. No one knows the timetable, but it is clear that Israel is being steadily marginalized among nations. Once that happens, I don't think it will be long before Jews are once again marginalized as a people, and effectively chased to the only safe haven remaining. The cycles of history turn slowly, but once they turn the hammer of change falls quickly. The current state of affairs is very precarious.
Maybe Biden can recommend that America be partitioned into three separate countries: One for the Democrats, one for the squishy Republicans, and one for the Conservatives.
