Pazhwak's liberal and progressive mindset, his advocacy for freedom of opinion, his support for active political participation of citizens, and his championing of human rights had fallen on fertile grounds particularly among intelligentsia. It became apparent that Pazhwak's views represented danger to the ruling establishment. While the new Afghan constitution was being prepared in 1963, Pazhwak (at the time serving as the president of the United Nations’ Human Rights Commission in Geneva) was asked by King Zahir Shahto return to Kabul to share his views regarding the constitution. Later on, however, Pazhwak learned with disappointment from an insider that his written thoughts submitted for consideration did not even reach the committee set up to discuss the articles of the new constitution. In 1973, when Daoud Khan came to power through a bloodless coup d'état, which had considerable support among the leftist and pro-Moscow elements of the Afghan army, he relied on Pazhwak as a special envoy to promote Afghanistan's national security interests in major international forums. Once again, Pazhwak was denied a leadership role in domestic Afghan affairs during the republican era of 1973 to 1978. The new republican constitution ratified established a one-party system despite Pazhwak's best hopes. Pazhwak was kept outside of the country, spending the 1970s far away from Afghanistan taking charge of the Afghan embassies in Bonn, Delhi and London.
