“The heart of a king is in the hand of Hashem” (Mishlei 21:1.) What a ruler actually does while in office is up to Hashem. So we should pray, do teshuvah, do other mitzvos, etc. And try to influence government policy the best we can, though without wasting time on activism that won’t make any different.
We should also try to influence American society to get closer to Torah values and practices — all of them (that are relevant to non-Jews), not just the ones Republicans seem to care about. That’s how we’re supposed to be a light to the nations — spreading the truth of the Torah to everyone (see Horeb by Rav Hirsch).
Israel is not “finished.” The status quo continues: Obama, and the rest of the world, advocate for a Jew-free Palestinian state, and Israel makes slight concessions but does what it wants, knowing that the two-state solution is never going to happen. The hearts of Israel’s rulers are in the hands of Hashem too.
