Well, you will not be surprised to find out that the Tangerine Tyrant has threatened the EU with constraints on supplies of Liquified Natural Gas (LNG) from the USA (now that global supply is constricted by the US/Israeli attack(s) on Iran), if they fail to pass the delayed EU/US trade deal without amendments.
So having delayed the ratification with his threats to Greenland, Trump is now using his disruption of LNG markets to drive his trade agenda.
Once a bully...
