It has nothing to do with happy communist alliance horse shits.

Cubans help Maduro because of freee 80% Venezuela oils. Without these oils, Cuba's economy collapses because Cubans don't have money to buy 80% oils from other countries. Russians or Chinese won't offer free oil to Cuba.

Chinese and Russians have wasted billion after billions dollars for Maduro's oil company because they want to build military bases in Venezuela because Cubans won't let them do so. They want to use these bases to negotiate with US later on.

Cubans, Chinese, Russians, and Irans don't help Maduro because he is a good communist or any shit you want to prefer. They help Maduro in order to save themselves from US.

What Maduro gets in return? money, 'artificial supports', and 5-minutes hall of fame on media.

Maduro should have sticked with his bus driving business or being a good happy communist like his previous boss instead of putting his name on US national security list.

Maduro is dumb enough to be used by these countries. He is paying for it with his presidency and his life. Free billion dollars years after years? Time to pay the debt is up, Maduro.
