Venezuela has been hit by a nationwide electrical failure due to a problem in a large hydroelectric dam.

Opponents of Maduro say it is his fault, but give no proof. Maduro says it is sabotage, but gives no proof.

I suspect both are partly at fault: that it was caused by US sanctions combined with Maduro's bad management.

US right-wingers are using fake news to push for intervention in Venezuela.

Note, though, that Venezuela's constitution does, however, authorize the head of the national assembly to declare perself interim president and hold elections. That aspect of what Guaidó has done is not the outrage they present it as.
