Apart from Gaddafi, Saddam Hussein & Thatcher, which other post WW2 leaders have been deranged whilst in power?

Thatcher ?come on honestly you lefties are really confused she had her faults but you can't put her on the same level as the likes of Hussein that's outrageous.Now let me think Castro for a start the lefts favourite dictator still alive and of course Uncle Joe Stalin we still have deluded left wingers who think he was not that bad Chairman Mao was of his rocker as is that bloke from North Korea interesting how they all seem to lean to the left don't they.Tory? sorry i am not a supporter of the Tory party as i said did not think she was all great but she was not deranged either it seems you have a few supporters here spouting emotive nonsense . Reagan was ok helped to end the USSR did not like Bush Snr Junior i felt sorry though awful time and decisions to make and bad advisers. I am a supporter of UKIP or the English Democrats so yes more to the right because of the issue of the EU but the Tories under Cameron are a joke.
