simple explanation
the cabel is screeching cause they're not getting anything out of their syria gambit but israel is getting a payoff.
like many things trump, hes simply acknowledging something israel ALREADY OWNS, hes just saying it publicly, and hopefully getting something out of it for US.
i mean honestly, under what possible scenario does syria kick the JDF off those hilltops and take that land back that doesnt end with somebody eating atoms?
