On his first trip to Cuba during his third term in office, Brazilian President Luiz Inacio Lula da Silva called the embargo imposed by the United States on the island "illegal" and denounced the island's inclusion on the list of state sponsors of terrorism.
No it isn not illegal and you’ll have difficulty proving that like others have.
We are embargoing Cuba yet most of the EU trades with them so it really sounds like you don’t know what embargoes are.
For example Havana Club rum is sold throughout Europe and Europeans can spend money in Cuba without reprisal. What they can’t do as per our agreements is sell them arms.
