Sanders-Vance.

I'd vote for that bi-partisan ticket for president.

Focus on America.  Don't fund Netanyahu and Zelensky.

Let supporters privately contribute to the "defense" of Israel and Ukraine.

How long until the billions are gone and those two countries are back asking for more US protection from the consequences of their actions?

If they pay for the weapons themselves, they will likely be more careful how the ammunition is used, and be more realistic in what can be accomplished by weapons.  There's no incentive to negotiate an end to any war America is financing... And when we are attacked?  Our allies will not be able to provide a defense for US.
