The First Sea Lord, Admiral Lord Mountbatten, and Chief of the Imperial General Staff, General Sir Gerald Templer supported the development of a hydrogen bomb, but preferred more support for conventional forces. They believed that the large American and Soviet nuclear forces acted as mutual deterrents for nuclear war, making conventional war more likely. Others proposed that, instead of repeated unsuccessful attempts to increase cooperation with the Americans, Britain work with Australia, Canada, and other Commonwealth countries. Britain could not disclose atomic information to Australia despite testing weapons there because of agreements with the United States.
