Much of the blame for the global warming hoax should be laid at her feet. She was an early and strong booster of the IPCC. And I don’t doubt that she knew it was a hoax. She did it, and funded it, to further her battle with the coal miners’ unions. And she wasn’t all that much of a nationalist - she actually gave a foreign country - the Republic of Ireland - a measure of sovereignty over Northern Ireland. Which is just another way of saying that the IRA’s attempts at killing her were at least partially successful. I like the fact that she helped the United States defeat the Soviet Union. That was certainly a positive thing. And her general tendency against socialism, it goes without saying. But let’s not get carried away.
Apparently she left us one of her cabinet members, Lord Monckton, to undo that damage.
She recanted her early views, and its obvious she was unduly influenced by others. I think she thought it genuine at the time.
I dont agree with your equation of her green policies (which were in the late 80’s) to her miners battle (which was 1984-85).
I agree her Anglo-Irish agreement (1985) was flawed, however thats rather moot now as the 1998 Good Friday Agreement meant the ROI gave up any claim to NI.
