Economic limits to US exceptionalism, undermining rules based order, UK election

Excellent essay on the macroeconomic limits of US exceptionalism and what it means for the increasingly protectionist global trading regime and the resurgence of mercantilism.  Is the US undermining the rules based order that it was a chief architect and proponent of in the post-WW2 period?  A rain-drenched UK PM Rishi Sunak announced an earlier than expected general election date in the courtyard of 10 Downing Street.  Is this an omen for a Conservative washout in the July general election?
