Carter's approach tells us what he would think. Carter was willing to give the Israelis and the Egyptians massive amounts of aid, conditioned on peace. That is very different than offering one side unconditional support despite that side allowing extremists to formulate and shape plans.
That's rather similar to what we have or going to have. Both Israel and Gaza may receive - keep receiving - external aid. The difference is that peace around Gaza, today's and tomorrow's, is going to be enforced more elaborately.
