Why NATO refused a no-fly zone on 4 March 2022

What did Ukraine's allies decide to do, and not do, on 4 March 2022? The day offered a clear answer: they would tighten financial and diplomatic pressure on Moscow, but they would not take steps that could put NATO forces directly against Russian aircraft.

The no-fly zone decision

NATO announced on 4 March 2022 that it would not declare a no-fly zone over Ukrainian airspace. The stated reasoning was that such a declaration could open an avenue for further escalation, because it could enable NATO nations to potentially fire upon Russian aircraft in the area.

President Volodymyr Zelenskyy condemned the refusal. He said that everyone who died from that day onward would also die because of the alliance's weakness and disconnection. The exchange set out the gap between Kyiv's request and the alliance's assessment of risk.

There was, however, a form of closer engagement that did not carry the same risk. By a unanimous vote, Ukraine became a contributor to NATO's Cooperative Cyber Defence Centre of Excellence on the same day.

Fighting on the ground

The military picture that day showed pressure on several fronts. Ukrainian officials confirmed that the power plant at Enerhodar had been captured by Russian forces. In the south, Russia renewed its assault on Mykolaiv with naval gunfire support, and the Ukrainian Navy scuttled its flagship frigate, Hetman Sahaidachny, at the port of Mykolaiv to prevent its capture.

In the east, Ukrainian air defences shot down a Russian Sukhoi Su-25 jet over Volnovakha in Donetsk Oblast. Near Kyiv, Sky News chief correspondent Stuart Ramsay was shot and wounded by Russian troops.

From within Russia's leadership circle came a call for harder action. The head of the Chechen Republic, Ramzan Kadyrov, urged President Vladimir Putin to let his forces seize Ukraine's major cities, saying this was the only way to save the Russian people and the state.

Pressure short of force

If direct military intervention in the air was ruled out, economic and informational measures continued. Italian police seized the yacht of Russian oligarch Alexei Mordashov at the port of Imperia. Another yacht, owned by Putin associate Gennady Timchenko, was blocked at the same port and was expected to be seized shortly. Both men had been sanctioned by the European Union.

Russia moved in the information space too. It blocked access to the websites of BBC News, Voice of America, Deutsche Welle and Radio Free Europe/Radio Liberty, as well as to Facebook and Twitter, saying they spread false information about what it called the special military operation in Ukraine.

The human cost beyond the front

The war's effects were also felt in neighbouring states. The Czech Republic introduced a 30-day state of emergency as thousands of Ukrainian refugees arrived in the country.

What the day showed

Taken together, the events of 4 March 2022 outline a division of roles. NATO drew a line at measures that might bring its members into direct confrontation with Russian aircraft, a line Zelenskyy publicly rejected as inadequate. Allied governments instead acted through sanctions enforcement, refugee reception and cyber cooperation. Russia, for its part, pressed its offensive in the south and at the Enerhodar power plant while restricting foreign media and social platforms at home.

The gap between Kyiv's appeal and the alliance's answer was the sharpest public disagreement of the day, and it framed the other developments: the tools that remained available were mostly financial, legal and humanitarian.
