The very next day was the 14 July Revolution led by Abdul Karim Qassim. The Hashemite monarchy and Nuri as-Said were overthrown. Pachachi was promptly appointed Iraq's Permanent Representative to the United Nations in 1959 by Qassim's revolutionary regime. During this time Iraq formed a close relationship with the Soviet Union led by Nikita Khrushchev. Under Qassim, Iraq was a founding member of the Non-Aligned Movement in 1961 and Pachachi met with founding leaders Josep Broz Tito, Kwame Nkrumah, Jawaharlal Nehru, Fidel Castro, and Sukarno as a representative of his country. During his time at the United Nations he also met with well-known figures such as Patrice Lumumba and Malcolm X. The Qassim regime recognised the People's Republic of China and Pachachi argued very strongly for their inclusion at the United Nations. Despite the brutal 1963 coup which removed Qassim from power in Iraq, Pachachi remained the representative at the United Nations.
