“Negotiations on the admission of Ukraine to NATO should begin immediately,” Business Insider quoted her as saying.

Simonyte called it a “big mistake” to refuse to accept Ukraine into the bloc earlier, for which NATO is now in a “moral debt” to Kyiv.

On September 30, Ukrainian President Volodymyr Zelensky announced that Ukraine is applying to join the North Atlantic Alliance in an expedited manner.

NATO Secretary General Jens Stoltenberg then said that the decision on the membership of any state is taken by all 30 allies unanimously.

US Secretary of State Anthony Blinken said that the admission of new countries to the alliance should follow the established procedure.
