Is the worm turning?

I've always thought that the UK has been a puppet/client state of the US, since 1945. However, according to Seymour Hersh, David Miliband and the head of MI6 visited Syria without permission from the Americans. This really is a shocker. Reagan of course invaded the former British territory of Grenada without mentioning it to his friend Thatcher, but the British haven't done anything without clearing it with Uncle Sam since Suez, which was a disaster.

The way Hersh tells it, Cheney was furious. How dare the Brits use their initiative?
