Yes, they could really appreciate finally getting permission to have their own
cancer diagnostic equipment, dialysis machines, tons and tons of hospital, medical tools, machinery they have been forced to do without due to the fact the US's extra-territorial reach of the embargo forbids them to even purchase these things from other countries if the equipment has components in them which origignated in the US.
Other countries have protested these underhanded tactics for years and years. They do run the real risk of becoming a US enemy if caught trying to sell the life-saving equipment. If Cuba can secure the life-saving items somewhere, it must pay many times its price to buy it on the black market.
Other countries maintain there is actually a blockade in place, rather than an embargo, because the US actually forces other countries to not do business with Cuba, themselves. Grotesque, massive bullying against a helpless nation, brutally impacting the lives of Cubans needing emergency medical care in many cases. That should be illegal, and many countries insist the long reach into their business with Cuba IS illegal in international law.
