It's become an accepted fact among most Orthodox Jews that Obama is "the most anti-Israel president ever" and perhaps even an "anti-Semite"
I'm not here to argue whether his policies on Israel are damaging to Israel or not, nor whether the Iran deal was smart. That could be, and has been, argued ad nauseum.
What I do want to say is this. Given current trends of increasing international isolation of Israel, it's possible that in the future, say 20 years down the road, the US may very well have a president who is actually anti-Israel, one who cuts off aid to Israel, votes against Israel at the UN, imposes sanctions on Israel, and perhaps even threatens military action.
THAT would be what an actual anti-Israel president would look like. Calling Obama anti-Israel is beyond preposterous.
