The only part of the Quebec Agreement that troubled Stimson was the requirement for mutual consent before atomic bombs could be used. Had Congress known about it, they would never have supported it. The American veto over post-war British commercial and industrial uses made it clear that Britain was the junior partner in the Grand Alliance. Churchill in particular considered the Quebec Agreement to be the best deal he could have struck under the circumstances, and the restrictions were the price he had to pay to obtain the technical information needed for a successful post-war nuclear weapons project. Margaret Gowing noted that the "idea of the independent deterrent was already well entrenched."
