Why is the US the only country with an embargo against Cuba? Why do other countries oppose the US embargo and continue trading with Cuba?

So other countries claim to care about Democracy and human rights and all this other stuff and yet here they are doing business as usual with Cuba.

And its been shown that tourism from Europe is a big part of what keeps the Cuban economy afloat.

Not to mention that the EU is also one of Cuba’s largest trading partners.

The only reason the US embargo hasn’t been working is because other countries continue doing business with Cuba.

And so it makes me wonder why for the past 29 years straight countries have been condemning us even though Cuba doesn’t even have free elections or free press for that matter.
