The first post on this thread had a link to Peter Hitchens article which explains that she didnt actually destroy the unions at all,the clever career unionists moved off in a different direction and have taken over almost every institution in this country and turned them into loony left madhouses and that is probably doing more damage to the country now than the old knuckle draggers like Scargill etc, did in the 70,s.So in my book she didnt really win the war, she just won some very bloody battles that left a huge amount of collateral damage,much of which could have been avoided if she was remotely interested in avoiding it.But I have no doubt that she thought that anywhere outside the home counties was pretty much a hive of communism and she didnt give a toss what happened to it.
I think that any sane person would agree that the unions were a big problem and needed to be sorted,thats stating the obvious really. I would argue that an intelligent rather than a beligerent leader could have solved the problem properly (which she didnt) and not caused the amount of damage she did to so many innocent people.
