You can’t make an omelet without breaking eggs. And in this case, the Iron Lady had to break the eggheads of academia, the arts bunch, and the media. If she’d done nothing else, this would have been a tremendous accomplishment. We were blessed in the 1980s to have three great leaders who overthrew communism - Mrs. Thatcher, Pope John Paul II, and Ronald Reagan. Too bad they were succeeded by pipsqueaks who rode on their coattails - like the Bushes, John Major and Boris, and the current Marxist pope.
I’d strongly add Lech Walesa to your list.
