Janae,
“I think that if [the U.K.] tried to act how the United States has that neither side would receive it very well.”
“A good compromise leaves everyone unhappy,” goes the saying. But given how the U.K.’s vague promises and border arrangements helped create this mess in the first place, perhaps you are right.
The European Union as a whole doesn’t seem to favor either Israel or Palestine over the other, and it has less stake than either the U.S. or the U.K. Maybe the E.U. might be the better arbitrator?
