In 1974, with India carried out the test of nuclear weapons near the Pakistan's eastern border, codename "Smiling Buddha", Bhutto sought the United States to impose economic sanctions in India. Though it was unsuccessful approach, in a meeting of Pakistan's Ambassador to the United States with Secretary of State Henry Kissinger, Kissinger told Pakistan's ambassador to Washington that the test is "a fait accompli and that Pakistan would have to learn to live with it", although he was aware this is a "little rough" on the Pakistanis. In the 1970s, the ties were further severed with Bhutto as Bhutto had continued to administer the research on weapons, and in 1976, in a meeting with Bhutto and Kissinger, Kissinger had told Bhutto, "that if you do not cancel, modify or postpone the Reprocessing Plant Agreement, we will make a horrible example from you". The meeting was ended by Bhutto as he had replied: "For my country's sake, for the sake of people of Pakistan, I did not succumb to that black-mailing and threats". After the meeting, Bhutto intensified his nationalization and industrialization policies, as well as aggressively taking steps to spur scientific research on atomic weapons and the atomic bomb project. Bhutto authorized the construction of Chagai weapon-testing laboratories, whilst the United States opposed the action and predicted that it will lead to a massive and destructive war between India and Pakistan in the future. The atomic bomb project became fully mature in 1978, and a first cold test was conducted in 1983 (see "Kirana-I").
