We give aid to Egypt and have since they signed peace accords with Israel. If the Egyptians become hostile to Israel, I'm sure the administration will cease providing aid.
It is not anti-Israel to advocate a two-state solution.
I suppose alternatively, we could abandon that solution and demand that Israel complete the annexation of the West Bank and Gaza and grant their inhabitants full Israeli citizenship. But I suspect that too would be rejected in favor of maintaining them as stateless people without rights.
