Why would targeting anything in the Arab states be a major factor in a ceasefire when the Americans don't care for the Arab infra and Israelis would actually be glad for the destruction? The bases are heavily protected and if casualties/destruction happening there then that's part of the war and factored in; they would not be a major factor for a ceasefire.
As I have said multiple times here: Either increasing number of American casualties and/or major destruction in Israel would be force a ceasefire, that is if Iran would agree to a ceasefire after what happened since Saturday. The third, more distant factor is economic pain America itself.
Nah, I don't see a desire by Israel/America for a ceasefire at this stage.
