I think the people that would travel to Cuba will travel anyways (illegally); however, with the addition of an American embassy, it makes it seem a little less sketchy. I've wanted to go for a while, but I read a VICE article a while back that kind of turned me off on it. Either way, it's nice that were making progress. Lord knows we do business with countries way more fucked up then Cuba, including a few that we have serious history with...
BTW, wasn't this all started by other countries boycotting some summit if Cuba couldn't attend? Kind of makes you realize how politics are really just high school, even on an international scale.
