the ultimate involvement of the United States in any war determining the future of Europe". Thatcher's belief in the nuclear hypothesis "in the context of the use of American bases in Britain to launch an aggressive attack on Libya, that it was 'inconceivable' that we could have refused a demand placed upon this country by the United States. The Prime Minister supplied the reason why: she said it was because we depend for our liberty and freedom upon the United States.

He received a warm ovation from the mostly Nationalist audience and as he walked off the platform, he said the words Edmund Burke used on the death of candidate
