Time for American Jews to take stock of resources, power, and possible friends. Other than far-leftist freaks there is no future in the Democrat Party, and the GOP is now clearly signaling they want us out as well. Like Israel, increasing autonomy should be the primary imperative
for US Jews. I would propose building legal machinery, becoming a people of law, covenant and social order. That might be a minority position but it will bring its own allies--everyone against the mob and the vendetta, which is now the norm in both parties. And if the mob wins
we'll all have much bigger problems than antisemitism anyway. Follow the model of these little law firms that focus on suing and building cases against terrorists and their sponsors and scale them up to include defamation, incitement, negligence of governments protecting
criminals, legal defense for legitimate cases of self-defense against criminals so people feell someone has their back. There are very specifically Jewish concerns in there but there's also plenty for all law-abiding citizens. Pull out from the parties and build power elsewhere.
