>no-holds-barred sharing of intelligence and spying Citation needed, except that by definition there can't be one, because if there were such a public claim, and an un-shared piece of intel existed (that in theory would refute it), then that intel could not be used publicly to refute the claim. Since the claim is irrefutable, it is also invalid. So it's probably more accurate to say 'extensive sharing...'
