Zelenskyy pushes NATO membership as security guarantee while Kallas signals openness

On the 1,013th day of Russia's invasion, Ukraine's president made a straightforward case: his country would not negotiate with Moscow until it had secured NATO membership, received substantial weapons shipments, and grown strong enough to dictate terms. Volodymyr Zelenskyy said this plainly on Sunday, adding that even skeptics within the alliance could be persuaded to support Ukraine's membership bid. "An invitation for Ukraine to join NATO is a necessary thing for our survival," he said.

The timing mattered. Kaja Kallas, the European Union's newly appointed chief diplomat, arrived in Kyiv that same day—her first official visit in the role, a deliberate show of solidarity. She came alongside Antonio Costa, the EU council president, both stepping into their positions just hours earlier. Kallas made clear that NATO membership represented the strongest possible security guarantee for Ukraine. But she went further, signaling that Europe should not dismiss any option, including the deployment of European troops to enforce a ceasefire. "We should have this strategic ambiguity around this," she said, meaning the EU would keep its options deliberately unclear to maintain leverage in any future negotiations.

Zelenskyy's position hardened the terms for any talks with Russia. He called for "steps forward with NATO" and what he described as a "good number" of long-range weapons systems. Only once Ukraine possessed these tools and had rebuilt its military strength, he argued, could serious negotiations begin. He insisted that both the EU and NATO participate in any discussions with Moscow. The framing was deliberate: Ukraine would not negotiate from weakness, and it would not negotiate alone.

On Friday, Zelenskyy had sketched a more specific vision. NATO protection for the territory Ukraine currently controls could end what he called the "hot war"—the active combat phase. That would leave the question of reclaiming Russian-occupied areas to be resolved through diplomacy later, once the immediate threat of invasion had been neutralized by alliance membership. It was a partition of the problem: military security first, territorial recovery second.

The diplomatic choreography reflected a broader shift in how Ukraine's leadership was approaching the conflict's endgame. Kallas's visit underscored that Europe's new diplomatic leadership saw Ukraine's victory as inseparable from European security itself. "My message is clear: the European Union wants Ukraine to win this war," she said. Kallas had stepped down as Estonia's prime minister to take the EU post, a move that itself signaled how seriously the bloc was treating the conflict.

Meanwhile, the war's grinding toll continued. Russian drone strikes hit the southern city of Kherson on Sunday morning, targeting public transportation. At least three people were killed and seven more wounded, according to regional governor Oleksandr Prokudin. Kherson had been liberated by Ukrainian forces in late 2022, but Russian forces had never stopped attacking from across the Dnipro River, using artillery and drones to pummel the city from territory they still held.

The broader military picture was shifting in ways that complicated Moscow's position. Syria, where Russia had maintained significant military presence for a decade, was collapsing. Rebel forces had seized Aleppo in a stunning offensive, exposing how thin Russian military resources had become. Moscow had redirected much of its military capacity toward Ukraine, leaving its Syrian ally vulnerable. "It was not Kyiv that fell in three days, but Aleppo," as one analysis noted—a reminder that Russia's overextension in Ukraine was creating vacuums elsewhere.

Germany's foreign minister, Annalena Baerbock, raised another complication: China's role in sustaining Russia's war effort. She accused Beijing of providing weapons to Moscow while claiming to support peace. "Instead of taking responsibility for peace and security in the world as a permanent member of the UN security council, China is opposing our core European interests with its economic and weapons aid to Russia," Baerbock said. She planned to raise the issue directly during a visit to Beijing the following week, arguing that European and Indo-Pacific security were now inseparably linked. North Korea's deployment of troops to fight alongside Russia, combined with Moscow's support for Pyongyang's nuclear program, illustrated how the conflict had become genuinely global.

On the nuclear question, the White House moved to close off one speculative avenue. Jake Sullivan, the national security adviser, said the Biden administration was not considering restoring nuclear weapons capability to Ukraine—a possibility that had circulated in some Western policy circles. Instead, the US would continue surging conventional military capacity to Ukraine. The focus remained on weapons systems Ukraine could use immediately, not on reopening questions about nuclear deterrence that would take years to resolve and would fundamentally alter the geopolitical landscape.
