Although Carter placed an embargo on Pakistan, Bhutto under the technical guidance and diplomatic though Foreign minister Aziz Ahmed, succeeded to bought sensitive equipment, common metal materials, and electronic components, marked as "common items", hide the true nature of the intentions, greatly enhance the atomic bomb project, though a complete failure for Carter's embargo. Bhutto tried to resolve the issue, but Carter intentionally sabotages the talks. In a thesis written by historian Abdul Ghafoor Buhgari, Carter keenly sabotaged Bhutto credibility, but did not wanted to favor his execution as Carter made a call to General Zia-ul-Haq to stop the act. Therefore, senior leadership of Pakistan Peoples Party reached out to different country's ambassadors and high commissioners but did not meet with the U.S. ambassador, as the leadership knew the "noble" part played by Carter and his administration. When Carter administration discovered Bhutto's act, the programme was reached to a well-advanced level, and furthermore, had disastrous effect on SALT I Treaty which was soon collapse, a failure of President Carter to stop the atomic proliferation and arm race between the Soviet Union and the United States heightened.
