No Politician in the modern era (or perhaps ever) divides opinion quite line Margaret Thatcher but I think first and foremost it should be recognised that the loss will be felt deeply by her close family. Of course not all that she touched could end perfectly, no Politician ever has a perfect record. It is easy to sight the Poll Tax, the sale of the utilities and of Council Housing stock, deregulation of banking etc (all things that we are still dealing with the effects of) were ill advised however it is pretty easy to forget just what a state and an International Joke Britain was when she took office -we couldn't even empty the bins or bury the dead without striking - it was a ludicrous situation whereby Unions were killing the very industries that they claimed to want to protect. Then of course there was her one and probably most defining moment - the Falklands War. This not only helped to save the Islanders from colonisation but also reaffirmed Britain's World Status not least with the United States.
The biggest evil in recent British Politics is not Margaret Thatcher. She had an almost impossible job of taking on militant forces which were literally destroying the Country. This was only ever going to be pretty messy & a largely thankless task. The biggest evil is a certain Anthony Charles Lynton Blair who had the fantastic opportunity to build a new and better society out of the ashes that Thatcher to a certain extent had to create. She had to and did sweep away the old, Blair had the mandate and crutially the strong and growing economy with which to be the "new, fairer Britain hero" He failed miserably, blew billions and started illegal wars. I'd dance on his grave before Thatcher's anyday.
