45 years is most of a lifetime!
You can't say 'Yes they lacked liberty' as if that's a minor point! I sometimes think, 'Never mind about To Kill A Mockingbird'. Why isn't 1984 on the GCSE syllabus?' Having to wear a burka is the least of the indignities of living in a totalitarian state with secret police and spies. The Hitler Youth? Telling tales about their own families.
Ordinary, decent people, in sufficient numbers, do not rise up against a brutal tyranny unless THEIR lives are made intolerable and they have nothing to lose. It was never more than a few who tried to get rid of Hitler. There was popular support for his anti-Semitic legislation. Saddam committed atrocities against the marsh Arabs and the Kurds which people did know about. But the ones who might have led a revolution were in exile., or executed. I once discussed the gassing of the Kurds with a Sunni young woman. 'But they're not Arab,' she said. With an airy wave of her hand.
Life was hard for everyone after WW2 - the Dutch were starving and we were financing the relief work in Germany when living through austerity ourselves in a bankrupt country. But from the 50's onwards, the West became more prosperous and the gap between us and the countries on the other side of the Iron Curtain was v obvious. That's why travel was so restricted.
And what about China? The Cultural Revolution? People will put up with an awful lot if they're frightened for themselves and their families.
Egypt, Jordan? IS are not in control there yet. They are acting because they see them as a threat. Rather belatedly.
