I've been seeing more gusanos active online pushing for "freedom" for Cuba amid the protests in Santiago. We know that the material situation is not good because of the embargo, how can foreigners help the party and people with material goods/resources?
Boy I read the question and was ready for some beef in the comments but you mean actually help the Cuban people lol.
Our party in Belgium has orgs that support Cuba like Cubanismo. You can become a member and donate money.
I hope others will reply with useful orgs in other countries.
