The regime in Venezuela isn't communist.It's more like an authoritarian socialist,populist corrupt regime.
A real communist regime means 100% state owned command economy and I think that there's something like a private sector in the economy of Venezuela.
I wonder how Maduro and the government in Venezuela managed to survive for so long.Is it because of the support of the army and some weaponized "red militia"?I don't know.Politics in Latin America has always been weird and exotic.US sanctions have an impact over the hyperinflation in Venezuela.We can't put all the blame on Maduro. 
Anyway,when communism fails,the communists say that it wasn't "real communism".
