On Saturday, a friend and I were comparing notes on the events following the U.S. raid on Venezuela. Setting apart all the questions about just what the White House is trying to accomplish in Venezuela, my most basic takeaway from the events of the last week is this: as President Trump’s popularity and power erode domestically he will respond with more aggressive assertions of power in those areas where his executive and prerogative authorities remain unbounded, where his domestic popularity matters the least. (This applies most obviously, though not only, to his military powers overseas.) Anything else wouldn’t be consistent with Trump’s character, which is inflexible and unchanging, though perhaps hardening with the progress of advanced age. The current situation between the U.S. and Venezuela shows how jagged, unstable and uneven this may become.
