The FT's source briefed on President Volodymyr Zelensky's recent trip to the U.S. did not provide further details.Zelensky presented his five-point victory plan to Biden at the White House on Sept. 26. The plan includes military and diplomatic components, including Ukraine's invitation to join NATO, but the full details of the peace framework have not yet been publicized.According to the information obtained by the Kyiv Independent, Kyiv had planned to ask for NATO membership within the months, not years.Biden previously said that peace in Ukraine means a guarantee that Russia will never occupy the country again, but Kyiv's membership in NATO is not necessary for this.Later in June, Zelensky and the U.S. president signed a security agreement between the two nations, which was described as a "bridge" to Ukraine's future NATO membership.
