I agree with Avi. It really does “smell of vindictiveness,” especially given the tweets and other messages that Pres. Trump has given. And don’t forget that this isn’t just US news – the world is paying attention. Every time the current administration does something that isn’t normal by accepted standards, it reinforces the impression that the US is no longer run according to accepted principles, and that it can’t be relied upon diplomatically, economically, or even militarily. That’s going to hurt.
And it’s really going to hurt Israel too, because we’ve relied on US backing so much in the UN and otherwise. The Israeli economy is no longer a bunch of kibbutzim and moshavim selling fruit to Europe (as it was when I lived there). It is now completely enmeshed in the world economy, and vulnerable to all kinds of economic and political maneuvers. People abroad are getting really annoyed with having to worry about figuring out what Trump is going to do next, and that negative attitude is going to spill over and reinforce the anti-Israel feelings that already exist. With some friends, you don’t need enemies.
