NATO weighs Ukraine's future in alliance amidst wariness and risks.

NATO leaders are discussing ways to provide "security guarantees" to Ukraine to prevent future attacks from Russia, but are wary of being dragged into a wider conflict. NATO Secretary-General Jens Stoltenberg said that while consultations are ongoing, there is no easy solution to the issue. NATO does not provide weapons to Ukraine and defends only the territory of its member countries. Ukraine has applied to join NATO, but most allies oppose letting the country in at a time when a war is raging. Stoltenberg expects NATO leaders to endorse Ukraine's membership aspirations at their summit.
