The three stumbling blocks to a Ukraine peace deal

A month in, and the war in Ukraine looks very different to how anyone expected. On the first day of the invasion, western intelligence sources believed that Kyiv would fall to Russian forces within 72 hours, underestimating the Ukrainians’ ability to defend their territory and overestimating the Russian military’s capabilities.

Among Vladimir Putin’s many errors was his underestimation of western unity. He did not predict the severity of the sanctions against Russia or that his act of aggression would snap Europe (most notably Germany) out of its complacency over defence spending. In some ways, Putin, by going for a full-on invasion, made it easier for the West to adopt a unified position. If he had instead developed things more gradually, he would almost certainly not have been met with such a response.

In the hours after the conflict began, the debate in Whitehall was about whether western unity would hold if Putin successfully installed a puppet government in Kyiv.
