For starters, how the fuck do you enforce an embargo without the threat of violence, and secondly I love how me and all my communist friends are expected to have a PhD in world history and economics while your average liberal can cite two state department links and a CIA funded NGO and call it a day.
One of the things I'll continue to say I liked about Obama was the gestures towards lightening up on Cuba. Not that they'd add up to anything, but hell, it seemed like the cold war status quo might get left behind to me at that point.
