She was "of her time". The UK had got a bit soft and lazy, (as a country perhaps, rather more than her people). After years of appeasement to (some would say, deliberately) destructive organised labour, someone, Maggie, stood up to them. I am of the "soft left", I hated Maggie, but what she did was necessary at the time. She stopped, at a stroke, hijackings of UK planes, by making it clear that no planes that were hijacked would ever be allowed to enter UK airspace and leave again.
Most importantly, for most of the Western world - She went to war to defend a small British colony in the South Atlantic. Just in case anyone thought we were a "soft touch" - they didn't think that afterwards. The world became a safer place. I still didn't like her - but she was necessary. Did any of that make sense?
