The upshot appears the US coordinated planning with Israel, but possibly at a level where it never reached Trump before the event that planning that way existed. Roosevelt did not know all Eisenhower and the Generals planned during US participation in WW II. But the gas field was a big escalation.
From that, neither Israel nor the US will attack the gas resources unless Iran further attacks Qatar's. A standoff.
Trump may be lying. It would fit his past statements, where trustworthiness hangs.
