May I congratulate the Prime Minister on his election victory, and particularly on the very strong commitment he gave at the beginning of his campaign to the maintenance of the strategic Trident nuclear deterrent in the future? Does he agree that, if there had existed in 1914 or in 1939 an organisation like NATO that committed America to the protection from day one of countries such as Belgium in the one case or Poland in the other, those two terrible conflicts might well never have broken out? Does he therefore share my concern that the virus of isolationism is again on the move in certain parts of the American political spectrum?
