Yes, they all have been on the list of the 10 Worst Dictators!
Kim made it at #2 in 2007.
Omar made it at #9 in 2007.
And Fidel made it at #15 in 2006. (He's slipping, didn't even make the list in 2007).
Oh wait, there's more! All three have come out and endorsed Barack Obama for President, joining recognized terrorist groups like Hamas and FARC.
Kim's state publisher in Japan: "We will see a better relationship between the U.S. and the Korean Peninsula with Obama, who sternly criticizes Bush and who would meet the leader of Chosun without pre-conditions, than with the “Bush clone” and scarecrow of the neocons McCain." (http://freekorea.us/2008/06/22/obama-gets-another-unwanted-endorsement/)
Castro on Obama: "the most-advanced candidate in the presidential race." (http://latimesblogs.latimes.com/washington/2008/05/obama-castro.html)
And finally, Qaddafi: "We still hope he will be proud of Africa and change America and free America of its past policy, namely with the Arabs," in addition, he claimed that Israel assassinated JFK and Obama feared a similiar fate hence the candidate's now-public support for Israel. (The Democratic Jewish lobby apparently had nothing to do with it). (http://www.haaretz.com/hasen/spages/991948.html)
If you're not already convinced to vote for Obama, keep holding out, I'm sure his team is working on edorsements from Iran's Mahmoud Ahmadinejad and Osama Bin-Laden.
