His 'place in history' is the only thing which has ever motivated the self-serving egomaniac.
I have no doubt that when Blair 'entered politics' his ambition was always to be Prime Minister. He simply chose the Labour Party because he was fully aware that a public school educated barrister was highly likely to rise rapidly through it's ranks – there was no such guarantee with the Tory Party. He did whatever he needed to, to reach the top including, joining CND – clearly something which he never had the slightest commitment towards.
Now that his plan to be remembered as a great war leader has been shot to pieces, the Middle-East Peace Envoy wants to be remembered as someone who brought peace to the world (just as long as it doesn't involve going into a war zone)
Give me a fully paid-up member of the Tory Party any day, instead of this liar, cheat, charlatan, and fraudster.
