On 14 September 2020, Ukrainian President Volodymyr Zelenskyy approved Ukraine's new National Security Strategy, "which provides for the development of the distinctive partnership with NATO with the aim of membership in NATO." On 24 March 2021, Zelenskyy signed the Decree No. 117/2021 approving the "strategy of de-occupation and reintegration of the temporarily occupied territory of the Autonomous Republic of Crimea and the city of Sevastopol."
Apparently Zelenskyy thought Ukraine had a chance of joining NATO, and was actively partnering with NATO.
I don't see any reason why Ukraine couldn't join us.
