So now the U.S. is about censorship?

We claim we want to bring democracy and Western liberties to other countries but then we actively try to suppress them when they are exercised?

Aren't rights for everyone, not just people we like?

If Cuba and Russia, or even Cuba and Canada petitioned the U.S. to stop the Radio Marti broadcasts, would we comply or tell them to put it were the sun shineth not?

Personally, I think taking out their transmitters and servers (either physical destruction or hacking) would be one of the extremely few acceptable uses of covert (as opposed to clandestine) action.
