The Nakba was known to have effected Al-Pachachi to such a large extent that the Iraqi poet Muhammad Mahdi Al-Jawahiri dedicated a poem to him entitled 'To Al-Pachachi in his Nakba'. 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 Although Al-Pachachi was no longer active in Iraqi politics at the time, he was a close supporter of Gamal Abd al-Nasser and was present alongside him and Shukri al-Quwatli in Cairo at the signing of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.
