I see, your opinion about Ukraine-Russia is not open tu debate. Let close that matter.

Refering Cuba, the problem, the undeveloment, the poverty and misery in Cuba is directly consecuence of the communist regime. Make the sanctions responsible is just don't know anything about Cuba except Government proganda (they are very good at that).

Some question maybe help you figure it out where is the main responsability.

Where is the trillions (more than the "Impact" of sanctions) that Cuba Communist Government receive from the USRR??

Why Cuba communist regime import from USA luxury cars, but when it come about ambulances say that the sanctions don't let them?

Why Cuba communist regime build with Cuban investment between 400-1000 millons dollars value hotels each year (that remain empty), but when it come about electrics power plants, hospitals, houses say that the sanctions don't let them do it?

Why even Russia and Chine don't give credit sale to Cuba?

Here is a little inside view about Cuba

PD: Communist regime will gladly sacrifice the people (they already do) for Exclusive benefits for them.
