NATO leaders have declared that Ukraine's future in NATO is 'irreversible', although no specific timeline for membership has been provided. This assurance was emphasized in a joint communique from the alliance's Washington Summit, reflecting ongoing support for Ukraine's democratic, economic, and security reforms. The U.S., Netherlands, and Denmark announced that NATO-provided F-16s would soon be operational in Ukraine. Concerns about potential escalations with Russia and the need for Ukraine to address corruption and systemic reforms were also highlighted. Ukrainian President Volodymyr Zelensky has sought firm guarantees for NATO membership, amidst fears of prolonged conflict. NATO Secretary-General Jens Stoltenberg confirmed that while Ukraine's membership is agreed upon, it will not happen immediately.
