When will people realize that Trump does this kind of stuff all the time and then undercuts our enemies at the last minute? He’s done this time and again and yet the hysterics on FR take the bait each and every time.
Every time Trump makes a move, most people on FR react just as you described. But none of these things are done without a reason, and this one is transparently simple. Like it or not, a lot of (allegedly) smart people who are highly influential in big corporations and global governments believe climate change is the result of human actions. Trump could choose to spit in their face and call them idiots (as most FReepers would have him do) which would put all of his international agenda in jeopardy and unbalance the growing economy which he badly needs to continue on course. So you send out a stooge who has high credibilty to put on the dog-and-pony show, meanwhile Trump and his team are continuing to MAGA and nothing alters his climate change positions.
