Imam Nabhani did actually praise ad-Daulatul makkiyah and his words have been published in copies of the book.
asak Imam Yusuf bin Isma'il Nabhani passed away in 1931. I did read somewhere that he was at the Rawdah of Sayyidina Rasoolallah saws when one of Imam Rida's devotees recognised the Imam and gave him one/some of Imam Rida's books. Imam Nabhani praised Imam Rida. Has anyone got details?
