I have several things in mind.
1. Immediately stop sending money, especially military aid, to Israel.
2. Do BDS against Israel until they agree to go back to the 1967 borders.
3. Sign into law a ban which absolutely forbids any lobbying on behalf of Israel.
4. Establish racial quotas in universities and various industries to ensure that Jews do not have disproportionate representation. These quotas should extend to appointed positions in government, and should be extremely restrictive. Furthermore, these quotas should also be applied, especially in the case of the government, to persons with Jewish conflicts of interest.
5. There likewise should be various housing policies to prevent high concentrations of Jews in various residential areas.
I have various other ideas in mind (e.g., requiring that they carry special identification, in order to enforce the quotas), but, generally speaking:
The Jews present a threat on Western civilization both domestically and externally (vis-a-vis the Jewish state).
With respect to the latter, they must cease to have any special status. They must be considered as no more or less special than absolutely any other nation state.
And with respect to the former:
I don't think that policies which very much resemble affirmative action policies would be out place with respect to the Jewish problem, because, in this case, we very much are dealing with a cohesive, self-interested group which, often enough, does not seem to have the interests of non-Jews in mind.
Just look at Trump's cabinet.
