Interesting, because CHRISTOPHER Hitchens has said he admires certain things about Thatcher and market-economics generally(claiming to be following in the foosteps of Marx, properly understood). Given his socially liberal views, one can postulate that his outlook is the mirror image of his brother's, ie. the market leads to social liberalism, and that's good.
Speaking of Christophher, while he didn't become a Yank until the mid-2000s, I think he had been more or less identifying as an American, culturally speaking and of course in terms of residency, conisderably earlier than that. But, given his religious views, I don't think he'd get anywhere in the politics of his adopted country. Much as he might have liked to imagine a nation of Paine-like freethinkers, there really isn't a lot of a market for that in the Shining City.
For that matter, he would probably have been too scabrous even for the land of Monty Python. There has to be a reason why the Brits, famously secular though they may be, see fit to keep the Church Of England in business, and I'd imagine that, while unlike the Yanks they don't demand absolute devotion from their leaders, blatantly insulting religious belief a la Hitchens would not go over that well.
And can you imagine the sort of relations the UK would have with the Muslim world under a PM Christopher Hitchens??
