Diplomacy and the U.S. role

The Russia-Ukraine war has settled into a brutal rhythm that both sides are escalating but neither can break. Russia launched a devastating combined arms strike on the night of October 18 to 19, firing 16 ballistic missiles and more than 200 drones, including jet-powered Shaheds, at Kyiv and 28 substations across 11 Ukrainian regions. More than 550,000 households lost electricity, heat, and water. Ukrainian President Volodymyr Zelenskyy said critical U.S. missile-warning support had briefly stopped and that Ukraine received no advance warning of the first wave of ballistic missile strikes from partners. The United States disputed any intelligence pause.

Zelenskyy's account of the warning gap matters because it goes to the credibility of the U.S. security commitment at the exact moment Washington is waiving sanctions on Russia and talking about a trilateral summit with Putin and Xi. Since mid-July, Russia has conducted 2,147 strikes against Ukrainian energy facilities, an average of more than 50 per day. Trump declared an "energy ceasefire" on October 11, and since then there have been more than 170 strikes on Ukraine's energy infrastructure. The ceasefire exists on paper and nowhere else.

Ukraine's response has been to take the energy war into Russia itself. On October 17 to 18, Ukraine conducted its largest strike against Russian digital, energy, and logistics infrastructure in St. Petersburg since 2022, hitting the VKontakte social media data center, the St. Petersburg Oil Terminal, an Ozon marketplace warehouse, and a cable-stayed bridge. Ukraine's Ministry of Defense announced that its strikes had knocked out 51% of Russian refining capacity, and the IEA reported diesel production fell by about 30%.
