I think it will take less time for western leaders to fall, and more time for economies to collapse. BoJo is gone (won't miss him). The longer the war in Ukraine goes on, the harder it will be for western countries to support the US-led Empire.

Africa is having to choose between letting their people starve and angering the west. After the first violent overthrow of a leader who chooses the former happens, the rest will choose the latter.

I think it is going to get a lot worse before it gets better.
