While free trade agreements are aimed at boosting trade, too many cheap imports could threaten a country`s producers, which could affect employment. However, the propulsion of the nuclear submarine has experienced difficulties. In accordance with the July 1956 agreement and an Eisenhower directive of February 1957, Royal Navy officers had been tasked with investigating the US Navy`s nuclear submarine program. In October 1957, its leader, Rear Admiral Hyman G. Rickover, felt that their questions were slowing down the use of Polaris` IRBM submarine at a critical time. He feared that any delay would push Congress to focus on land-based missiles. In December, British liaison officers complained of a slow response to their questions. Rickover proposed allowing Westinghouse to sell an underwater nuclear reactor to the Royal Navy, which would allow it to immediately continue construction of its own nuclear submarine. The British government supported this idea because it would save it a lot of money.   Article 2 of the treaty relates to the joint development of defence plans; Training of personnel on the ground and defence against nuclear weapons; the exchange of information and the assessment of hostile capabilities; The development of nuclear vector systems and the research, development and construction of military reactors.  The treaty requires the exchange of classified information on nuclear weapons when the communicating party finds, after consultation with the other party, that disclosure of this information is necessary to improve the recipient`s ability to develop and manufacture nuclear weapons.
 The United States would transmit information on British nuclear weapons. In the immediate future, this would exclude information on thermonuclear weapons.  Confidential information issues are also covered by the agreement. The UK government has not published these sections “due to the need for high confidentiality and the use that such information would be intended for other potential nuclear states. In other words, it could very well contribute to the dissemination.  The key was that he had the support of Carl T. Durham, President of the JCAE. On December 3, 1957, Eisenhower met with congressional leaders and insisted that he be more discreet in cooperation with all American NATO allies, not just Britain.  In fact, the government negotiated agreements with Australia, Canada and NATO.  Eisenhower has not yet supported the proposal, but U.S. Senator Clinton Anderson has not received much support.  On January 27, 1958, Strauss Durham sent the government`s proposed legislative amendments and the JCAE Subcommittee on Cooperation Agreements, chaired by Senator John Pastore, held hearings from January 29 to 31.
