@Frank Apisa,
You asked why I don't want American bases on our soil, what could have triggered such a feeling, and I've answered you. It was the Kate Adie report, I can clearly remember feeling shocked at what had happened and very angry that this war crime had been perpetrated from British soil. Thatcher hadn't even bothered consulting parliament.
I've got no problems with Americans visiting and working here, whenever I'm in London I tend to help out one confused looking American per visit on the tube. Those bases are something else, and the fact that they were used to perpetrate a war crime without any parliamentary oversight was an affront to our national sovereignty.
That feeling was only exacerbated by the invasion of Iraq and extraordinary rendition.
As Walt has pointed out, there's a strong divide between Labour and Tory governments. The Conservatives have always been a lot closer politically to the Americans, more free market anti collective than Labour, and Labour governments have often felt threatened by America. Harold Wilson was never forgiven for keeping us out of Vietnam.
Blair was a special case, he was as interventionist as Bush, something the party membership weren't aware of until it was too late. To my great regret I voted for Blair as party leader thinking he'd get us in to power. He did, but I didn't realise how far right of the party he was.
