I'm confused - your prior post indicated that calling out dictatorships for murdering their own people was some sort of inappropriate interference. Now you appear to be taking the opposite tack - that something more concrete should be done to stop dictatorships from killing their own people. Perhaps you could clarify which end of the candle you think should be lit?
As for why it is important to speak out when evil people do evil things - here is an article on Natan Sharansky and the impact Reagan's words had on the Soviet Union:
Hopes were raised for such detainees as Sharansky when they learned from an article in Pravda or Izvestia that found its way into the prison that Ronald Reagan had proclaimed the Soviet Union to be an Evil Empire before the entire world. Following this proclamation there was a long list of most of the Western leaders who lined up to condemn the evil Reagan for daring to call the great Soviet Union an evil empire but for Sharansky it was the bright and most glorious day.
Finally a spade had been called a spade. Finally, Orwell's Newspeak was dead. President Reagan had from that moment made it impossible for anyone in the West to continue closing their eyes to the real nature of the Soviet Union.
For Sharansky Reagan's Evil Empire speech was one of the most important, freedom-affirming declarations of all time and he subsequently saw it as the moment that really marked the end for the Soviet system, and the beginning for dramatic changes. A lie had been exposed that could never, ever be untold now. This was the end of Lenin's "Great October Bolshevik Revolution" and the beginning of a new revolution, a freedom revolution - Reagan's Revolution.
Sharansky actually attributes the collapse of the Soviet Union not to Ronald Reagan alone but to three men who brought moral clarity to the conflict and started the chain of events which led to the end of Soviet communism. These men were Andrei Sakharov whose dissidence encouraged those amongst the Russian people who were dissatified with the Soviet system, Senator "Scoop" Jackson who helped the American government to end its appeasive co-operation with the Soviet system whilst Ronald Reagan on behalf of the American people encouraged greater moral clarity in the world and thus in to the Soviet Union.
My point was that resolutions are worthless.
