Heinz Dieterich is a sophisticated intellectual, economics professor at UNAM, and coined the term "21st Century Socialism". Dieterich was very close to Chavez, but he was pushed back and dismissed from the inner circle together with Saman, Baduel, and other individuals who weren't boot lickers.
You can quote from that site, and I can quote from my sites, and we won't ever agree, that's very clear. But consider where he was published: aporrea.org - a communist website which unlike Venezuelanalysis is truly independent, run by communists and willing to open debates. This is something many aren't willing to do.
Why is Doeterich linked to the story? I think Maduro is feeling a lot of pressure. That regime is crumbling, and they are reacting by causing external conflict. The measure taken against the seismic research vessel was completely uncalled for, and if indeed they arrested the Ukrainian captain this is starting to get incredibly bizarre. Today Ukraine is closely allied with Russia. And Russia has a lot invested in Venezuela (plus Venezuela owes Russian corporations a lot of money). So Maduro's ove to jail an Ukrainian, allied with Russia, is nearly irrational.
In that article you quote, they say the only way forward is to "strike blows and making the revolution irreversible". I calls for violence. But the fact is that today the majority of the workers in Venezuela are opposed to Maduro. He barely won the election in April (if he did win it), and since then he has shown that he's both incompetent and a weak leader. So what are these so called communist cadres going to fight with? First of all, they are mostly thugs or fascists. And second, they just lack the numbers. They may have the weapons, but I don't think they can force the people to accept being enslaved by a regime made up of imbeciles and thugs.
I suppose Maduro's handlers realize things are getting out of hand, and because they are Cubans they'll try to use the violent route (violence being the only method they understand to do politics because they were born and bred in a Stalinist regime). So my guess is the regime will turn to both raising external tensions to distract attention and violence will escalate.
Yesterday there was an intense firefight in Libertador municipality in Caracas, near the end of the Cota Mil. Chavista against Chavista armed with military rifles. Things got so bad one of the two sides took over Vargas Hospital. The doctors fled, the national guard was nowhere to be seen, and some doctors were sought in their homes and forced to work on the wounded - but only the wounded for the side which had taken over the hospital. Soon the sun will rise and there's going to be a body count, and I bet the official statistics won't show the number of dead. Chavismo is becoming utterly chaotic, there are internal divisions and soon there's going to be a shooting war. And jailing an Ukrainian captain won't save Maduro. I think Dieterich is right.
