Striking parallel between Trump and Liz Truss: The power of economics/markets to turn even your own side against you. Trump isn’t losing any support over his performative cruelty towards immigrants, but is rapidly losing Republicans over the economy, stock market, inflation etc

This is a moment of testing for Donald J. Trump's advisors. The intellectually honest ones know that this reflects the President’s 40-year fixation, not any kind of a proven economic theory. This is the economic equivalent of what creationism is to biology or what ending

A 3-way game of chicken is being played between Trump, Powell and Xi. The strike price for the Powell put is much lower than for Trump put. And Xi’s put strike live is even lower; thus Xi will let Trump bleed for now in this retaliation Nash game. This is a 3 dimensional chess

Starting to think that in order to unravel this mess, we might need some sort of general agreement on trade and tariffs, perhaps housed under some sort of world trade organization. If we want to work closely with our neighbors, might I suggest some sort of north american free
