BRUSSELS – Nato countries are divided over what kind of political reassurances they might give Ukraine at the next Nato summit meeting in mid-July, with the United States, Germany and France resisting pressure from central and Eastern European allies to provide any detailed “road map” towards membership, Western officials said following a meeting of Nato foreign ministers this week.

On some level, they said, the debate is notional, given that Ukraine is at war and a major part of its territory is occupied by Russian invaders.

Also, much will depend on how successful Ukraine is in its long-heralded counteroffensive, expected later this spring or early summer.

The debate was one focus of the meeting of Nato foreign ministers in Brussels this week, as it was for the previous such meeting held in Bucharest, Romania, in November. Back then, the US also resisted making any political promises to Ukraine about accelerated membership.

Ukrainian President Volodymyr Zelensky has said that he will come to the midsummer Nato summit meeting in Vilnius, Lithuania, only if he is given some concrete path or enhanced steps towards Nato membership.

Ukraine applied to join the alliance in September, but Nato officials understood the application to be a question for a more peaceful future.

Ukraine would also like some concrete assurances about security guarantees that Nato could offer it once peace is established. The kind of assurances and longer-term partnership that Nato might have with Ukraine, short of full membership, is another divisive issue.

Nato members will continue to discuss what they are collectively prepared to offer to Ukraine in Vilnius, but it will not be easy to find a compromise that is more than symbolic and that will satisfy Kyiv.

“We have got several weeks of hard negotiations ahead to close those gaps and craft a political outcome,” one Western official said.

But some of Ukraine’s neighbours have been pushing for a path to membership, including Poland, the linchpin of Nato’s eastern flank. While on a state visit to Warsaw, Poland, on Wednesday, Mr Zelensky won strong backing for a rapid entry into Nato from Polish President Andrzej Duda.

US Secretary of State Antony Blinken, asked on Wednesday about whether some proposal about membership might come at the meeting in Vilnius, said that it is more important to concentrate on “the very practical steps” to get Ukraine’s military trained and equipped for the counteroffensive.

“Our focus right now is relentlessly on doing what needs to be done to help Ukraine defend itself against the Russian aggression and, indeed, to put it in a position to retake more of the territory that has been seized from it by Russia,” he said. “That is our intense focus.”

Mr Blinken added that Nato is “also looking at what we can do, over a longer period of time, to build up Ukraine’s capacity to deter aggression, to defend against aggression and, if necessary, again in the future to defeat aggression”.

“And a big part of that is bringing Ukraine up to Nato standards, and to Nato interoperability. And I suspect that you will see that focus continue at the Vilnius summit.”

In 2008, Nato leaders promised Ukraine and Georgia eventual membership, but without setting a date.

Russia went to war against Georgia that year, and Russian troops remain in parts of Georgia, as they do in large sections of eastern Ukraine and Crimea, which Russia illegally annexed in 2014.

“Of course, Nato’s door remains open,” Mr Blinken said. NYTIMES
