There's been a good amount of threads with this question you can search for that have great answers, but IMO the US and the rest of the imperial core, as per Lenin's law that capitalism breaks at the weakest links in the chain, will be the very last countries on earth to have a revolution.
The US empire will fade out of history the same way the British and Roman empires did, with a pathetic, hundreds of years long whiny decline into political turmoil and international obscurity, while it eats itself internally and depopulates as its poor leave or are sacrificed on the altar.
Anarchists can't have a successful revolution because they can't organize installing a light bulb, let alone organizing cross-industry production or a coordinated military defense of a city. It had its go in the 19th and 20th century and failed, and should only be studied by historians as an intellectual curiosity, like blanquism.
