Antony Blinken’s unannounced visit to Kyiv on Tuesday was a welcome and timely show of support. It was the US secretary of state’s first trip to Ukraine since America belatedly signed off on a $61bn aid package last month, allowing a desperately needed supply of new arms to finally flow to troops in the east. As Mr Blinken met President Volodymyr Zelenskiy in the capital, events continued to underline how urgently such assistance – and much more of the same – is required.
The ultimate scope of Russia’s significant offensive in the Kharkiv region is yet to become clear. In part it may be intended to create a buffer zone, protecting Russian territory close to the north-east border. But as thousands of residents are once more displaced, and the prospect looms of a huge artillery assault on the city of Kharkiv, the incursions are also diverting threadbare Ukrainian resources from the eastern front. That may facilitate new Russian breakthroughs in the Donbas region.
