So Obama bans a believed member of a terrorist organization and Israel bans two US congresswomen and you are drawing equivalencies?! Really?
In fact, when the Obama administration was challenged on this decision, they were unable to present evidence of membership in any terrorist organization, but clearly he held views Obama disapproved of. However much Obama may have disliked Michael Ben Ari's political opinions, his presence here in the US would have provided no danger to Americans, but in the volatile situation in Judea and Samaria and Jerusalem where the two intended to go, attempted terrorist attacks against Jews occur everyday and if they continued their anti semitic and anti Israel rants there they would likely have incited more violence. Obama made a political gesture based only on his personal political biases whereas Netanyahu made his decision to prevent violence in Israel.
