I must say I've not followed this very closely and don't really know what to make of it. Chavez had my qualified support- seemed a good leader, made popular and necessary reforms, had the democratic backing of his country, a slight authoritarianism that was maybe justifiable given the circumstances. Maduro has long seemed like a desperate man, losing his grip on a crumbling country and resorting to increasingly desperate measures to keep a hold on power.
I'm not sure what the justification can be for recognizing Venezuelan Perkin Warbeck as the rightful king, mind. Beyond the obvious realpolitik, obviously.
