From a New York Times story by Matthew Mpoke Bigg headlined “What Is NATO, and How Has the War in Ukraine Changed It?”:

Leaders of NATO countries are meeting in Vilnius, the capital of Lithuania, for an annual summit that is set to be dominated by the response to the war in Ukraine.

Europe’s largest war since NATO was formed 74 years ago has revived the grouping, returning it to its Cold War roots as a war-fighting alliance. It has also raised vexing questions about military aid to the government in Kyiv and the membership bids of Sweden and Ukraine itself.
