One of the worst negotiators in world history. Sets an artificial deadline, and when there is no movement on the part of the other side, our guy faces the choice of imposing tariffs and losing face, or 'revising' his deadline and looking foolish while still no closer to any of his '90 deals in 90 days'.
The nasty letters Der Dotard will reportedly send out this week will probably have the same effect--nothing.
Were I advising the countries threatened with tariffs I would advise all to engage slowly, so as to demonstrate a willingness to negotiate, but do so on a reasonable timeline. Have and keep to their negotiating position. The fatal flaw in the Trump administration's plan is that they they are relying on fast response, which can cause the other side to simply agree with what Trump and his minions are offering. Trump does not have the patience, analytical capability, intellect or negotiating position to work through protracted negotiations. He wants people to like him, which means that if they 'agree' with him on some point, he can declare victory and move on. String him out, wear him down, get him impatient, and he will give up most of what he seeks so that he can declare' victory', no matter how small or meaningless...
Why the face masks? I'll wager that sooner or later it will come out that a sizeable percentage of these ICE or other agents are nothing more than hired bullies and cosplayers, nothing more than stand-ins, wanna-be agents, Blackwater contractors, moonlighting cops from the outer burbs working on their day off or 1/6 criminals who got on with flexible employers. Nearly all will be on the Barney Fife protocol with no ammo in their guns and smaller 'sticks', just out to impress girls with their outfits...
