For their part, the British wanted the McMahon Act's restrictions on nuclear co-operation to be relaxed. They wanted to know the weight, dimensions, fusing and firing sequences, safety features, and in-flight procedures. That information would allow American bombs to be carried in British V-bombers and American warheads to be fitted to British Blue Streak missiles. That could save millions of pounds and avoid domestic political complications if Britain had to persist with nuclear testing during an international moratorium. While the British knew what they wanted, there was no consensus among the Americans as to what they wanted to provide. US Secretary of State John Foster Dulles was concerned that a special relationship with Britain might complicate US relationships with its other allies. Strauss, in particular, felt that a proposal to give hydrogen bomb secrets to the British would likely not get past the JCAE, and counselled drafting amendments that were sufficiently vague as to give the president the authority that he needed without arousing its ire. Eisenhower declared that the US and the UK were "interdependent" and pledged to ask Congress to amend the McMahon Act.
