If Gaddafi were a good ruler, then how come he supported terrorism and had an insane cult of personality and had all the hallmarks of a dictator? If it were up to me, he and every other leader in the Middle East and North Africa would have been tried for crimes against humanity and then summarily executed.
But, since I'm feeling rather vindictive today, I'm gonna do a variation on the usual "fixed it for you" meme. Pay attention, fellow commenters, 'cause this is directed at you.
"Castro was a good ruler. The US want him out of the way so that they can take the gold he accumulated instead of the worthless dollars he refused to accept. They also want to control his country to protect their interests at the expense of the Latin Americans. Make no mistake all these Latin America revolutions are supported and organised by the Elite American corporations who don't give a snuff about anyone, including the terrorists whom they use as disposable pawns."
Honestly, I will never understand why Europe and elsewhere seem to love Castro so much, or say that the US treatment of Cuba is unfair. Apparently just having a universal healthcare system is reason enough to ignore all the oppression that goes on in that country. It's extremely hypocritical of you.
