Worth remembering that Russia experienced three revolutions in the beginning of the 20th century: in winter of 1905, turning it into a constitutional monarchy at least de jure; in spring of 1917, turning that into a parliamentary republic; and in autumn of 1917, turning the parts that did not secede into a dictatorship that shortly became embroiled in a civil war. The Bolsheviks later did an impressive job of erasing the memory of the third being essentially a military coup against the second, despite their very name originating in (remarkably petty) name-calling in the parliament.
By the time the October revolution came, the Provisional Government had lost most of its popular support by choosing to continue WWI though.
Anyway, the main point is that as nice as getting rid of a dictator sounds, the consequences can be much worse than the dictatorship itself, at least in the short term (which can last for a decade or more…).
I sincerely wish the best to Venezuelans, but previous US toppling of terrible dictatorships don't have a stellar record to say the least.
Living in a country stuck in a decade of counterinsurgency warfare doesn't feel particularly great, and I'm sure the Iraqis or Afghans would agree.
