Evidence enough that the Anglo-American relationship is a debatable one may be found in the fact that it is debated, even at tedious length. Evidence that it is an alliance in any specific or bilateral sense might be harder to establish. All fifteen of the member-states of NATO, to be sure, are formally allies, and it is no doubt true, though not an officially defensible proposition, that some allies are more allied than others. But the claim that the relationship between Britain and America is of more significance, or better worth examining than, say, that between Norway and Turkey would have to look to other evidence than the formal words of treaties.
