Cuba needs a regime change*** Fidel Castro's recent wave of murderous repression against peaceful dissidents has again exposed him for what he has always been -- a brutal dictator. It has also debunked the lie that economic engagement and a ''more-moderate'' political line can help reform Cuba's Stalinist system. It's now painfully obvious that a decade of European engagement with, and coddling of, the Cuban dictator has failed miserably. For many, it's time to play hardball with him.***
