Is there a particular reason to take any state account of anything at all at face value? At some point you either have to accept to play the game or reject all news.
In this case, it fits squarely in with American foreign policy, especially their orientation towards Venezuelan chavismo.
Maduro lies about many things, so his claims in particular should be viewed with more skepticism than any other state account picked at random.
It also fits squarely with corruption in Venezuela, specially regarding energy. Venezuela has been rationing electricity across the country since 2009 and has been involved in countless corruption scandals involving Odebrecht, PDVSA, Derwick Associates.
I understand the US's foreign policy is a global threat, but let's not let that be an excuse for the atrocities and corruption of tyrants in Venezuela and other places.
