 Although he was not a founder of the "Free Officers", a Baathist-affiliated underground organization of anti-British Jordanian officers, he joined the group after being invited in 1950, following his return to Jordan.Abu Nuwar became a vociferous critic of British aid to Jordan, viewing it as a form of dependency on Jordan's former colonial ruler, and of Glubb Pasha, the influential British officer in charge of the Arab Legion who was derided by Arab nationalists as a symbol of lingering British colonialism in Jordan.When Abdullah I was assassinated in 1951, Glubb and Prime Minister Tawfik Abu al-Huda's government discussed preventing Abdullah's son and heir apparent, Emir Talal, a sympathizer of the Free Officers, from being enthroned; Talal had been checked into a mental institution in Switzerland, but many Free Officers believed the British were fabricating Talal's mental illness to keep him out of Jordan.
