NATO's stance on Ukraine's security assurances and enlargement discussed ahead of summit.

Ukraine is unlikely to receive a full invitation to join NATO while engaged in a full-scale war, according to the US ambassador to the alliance, Julianne Smith. However, NATO is still negotiating language to signal its long-term commitment to Ukraine and is trying to find a way to show that at the upcoming summit in Vilnius. Ukrainian President Volodymyr Zelenskyy has been imploring NATO leaders to put Ukraine on a concrete path to accession, but NATO is currently working on a two-part package for Ukraine, focusing on practical support and the political question of what rhetoric to use around Ukraine's bid.
