At least this would be a wonderful thing if Serbia ultimately decides despite
the present circumstances to make this come to fruition. These are a great people.
In the most twisted way, no. This deal makes Serbia moving their embassy to Jerusalem with recognition of a terrorist pit a negative thing.
Ted Cruz once probably quoted someone else saying "you have to make the political price of doing the wrong thing higher than doing the right thing". This isn't about Serbia or Israel now, it's about Trump. If Trump gets his low-information right wing support for getting Serbia to support Israel while recognizing some place they probably can't locate a map where it might be found on, now he knows we'll bend over and the only thing he has to do is appease evil to win.
He's going to get another "yay whatever" embassy move in exchange for recognizing a state of terrorists carved out of another state. Now the "peace process" that the UAE price very prickly tweeted he was happy about, what other terrorist states can we recognize carved out of infidel countries. I bet every single muslim state would want to move their embassies to Jerusalem with big embassies that take up as much of the city as possible full of guns and F-35s for them all hurray for peace!
Serbia has options. The national pride one is "we're not some sucker, we want more out of this deal America", and try to milk the Trump teet a lil, but Americans won't be prohibited from insulting you like they are when America helps African war zones and muslim terrorist holes. Might be worth the cash. The most righteous option I can think of that would get you front page news either way is to say that recognizing the Kosovo invaders is equal to recognizing a Terroristinian state, as a nation you do not support this and therefore you can't move the embassy as part of the deal, and invite Israel to craft a new deal outside of the Trump framework.
Now you didn't spit on Trump because you still can say well we improved on his initiative, massive boost to relations with Israel and pro-Israel people, thought at a cost of relations with alot of people that hate Israel, not that they usually are out to improve the world with what good people want.
Whatever you do you need to be making a propaganda campaign like your life depended on it. Who in America knows that Trump wants Serbia to recognize a terrorist hole carved out of the ashes of the Serbian buildings they burned and so they're making Israel do it?
