Executive Summary
The air war over Ukraine and Russia has sharply escalated, highlighted by a Russian drone strike on the central Security Service of Ukraine (SBU) headquarters in Kyiv, prompting President Zelensky to vow a "mirror" response. Concurrently, Ukrainian forces executed deep-strike operations across Russia, hitting an oil depot and an S-400 air defense system in Sochi, as well as petrochemical facilities in Bashkortostan, leading to the first international airline suspending flights to Moscow. Diplomatic efforts remain tenuous as Trump administration envoys Steve Witkoff and Jared Kushner plan a controversial trip to Moscow and then Kyiv, with Ukraine offering a temporary ceasefire on airstrikes during their travel. Meanwhile, Western financial and military support continues to face political hurdles, with a major US sanctions bill potentially delayed and Slovakia blocking an EU sanctions extension.

Analysis
The battlefield is witnessing a deepening strategic air campaign, with both sides leveraging mass-produced medium-range strike capabilities to target each other's critical infrastructure and civilian economies. Ukraine's strategy of pushing deep into Russian territory—including Bashkortostan and the Black Sea coast—is successfully disrupting Russian civilian aviation and military logistics, forcing Moscow to reckon with the war's domestic consequences. However, Russia continues its maximalist bombardment of Kyiv, directly striking government buildings and keeping the capital under near-constant air alerts, indicating that diplomatic trips or ceasefires hold little sway over the Kremlin's operational tempo.
What to watch next: Whether Ukraine executes its promised "mirror" strike on Russian security apparatus targets; the logistical outcome of the Witkoff-Kushner visit amid active combat; and the trajectory of Western military aid, specifically potential co-production deals for older Patriot interceptors or South Korean M-SAM II sales.
