Opposed, at least until the Senate also passes an Atlasia-Palestine Defense Treaty.
I am unaware that Iran is threatening to wipe Palestine off the map. Source, please?
Who said anything about Iran? Last time I checked, Israel isn't exactly a friend of Palestinian national sovereignty.
The reason the treaty was proposed was due to Iran acquiring nuclear weapons and thus posing a real threat to Israel's very existance. It formalizes our current ties with them and sends a message that we stand with them.
