I do think Obama's last change to Cuba policy is wrong. Of course, I'm for open immigration, so that goes without saying.
However, opponents of Obama's earlier reforms on Cuba policy don't have a toe to stand on. It is a perversion of US law to invoke the freedom of Cuban citizens as an excuse to limit the freedoms of Americans. Prohibitions on trade with and travel to Cuba are inexcusable restrictions on the freedoms of US citizens, and they are simply indefensible.
