I completely fail to see a problem with this.
The reason why you fail to see a problem with that is that you’re not following the election coming up in Israel. You’re looking at it from the perspective of someone in the American political system.
The problem is ... and what you continually see Netanyahu DENY is that this is a PARTISAN ISSUE, because the opponents to Netanyahu in Israel are saying that Netanyahu is destroying this special relationship with the USA by making it a Partisan issue. The opposition is making this to be a CORE ISSUE of their campaign against him. If they succeed in getting the Jews in Israel to believe that ... then they stand a VERY GOOD CHANCE of DEFEATING NETANYAHU.
You’ll notice that Netanyahu CONTINUALLY DENIES THIS ... and that’s because he knows he can lose on this one!
