But I think the American people expect more from us than cries of indignation and attack. The times are too grave, the challenge too urgent, and the stakes too high to permit the customary passions of political debate.

As Winston Churchill said on taking office some twenty years ago: if we open a quarrel between the present and the past, we shall be in danger of losing the future.
