During the 1930s he was under the surveillance of British intelligence services, declassified documents reveal that much to their chagrin he had close ties with the Soviet Union and the personal letters they have archived in his file show he was organising with the League Against Imperialism and Virendranath Chattopadhyaya.

On 14 July, Zionist activity in Iraq was made a crime punishable by death or life imprisonment by the Pachachi government.

The documents describe him coming to blows with the Jordanian Prime Minister Tawfik Abu Al-Huda over Hashemite policy towards Palestine.

He also opposed the 1951 law that allowed Iraqi Jews to leave the country, although he himself left Iraq that year, returning after the 14 July Revolution in 1958.

Although Al-Pachachi was no longer active in Iraqi politics at the time, he was a close supporter of Gamal Abd al-Nasser and was present alongside him and Shukri al-Quwatli in Cairo at the signing of the unity pact between Syria and Egypt thus forming the United Arab Republic in February 1958.
