UKRAINE STRIKES RUSSIAN AIRFIELDS AND REFINERIES, ADVANCES NEAR KUPYANSK
Ukrainian forces struck Russian airfields at Yeysk and Millerovo and the Kirishi oil refinery overnight, per the Ukrainian General Staff, ISW's August 30 update reports. ISW assesses these strikes, alongside a Kupyansk-area infantry advance, are part of efforts to degrade Russian strike capacity and restore battlefield maneuver.
AT A GLANCE
NEW | UKRAINE | ISW reports Ukrainian strikes on Russian airfields, oil refineries, and marketplaces alongside Kupyansk-area ground advances.
CARRIED FORWARD, AUG 28 | IRAN | Iran's leadership reportedly discouraged public discussion of worsening economic conditions while arresting protest leaders.
CARRIED FORWARD, AUG 28 | TAIWAN | Taiwan's legislature passed a NT$240 billion drone budget as China intensified anti-corruption scrutiny of its Rocket Force.
CARRIED FORWARD, AUG 26 | KOREA | North Korea reportedly rejected engagement with Seoul while Trump signaled openness to meeting Kim Jong Un.
WHY UKRAINE'S STRIKE CAMPAIGN AND KUPYANSK GAINS MATTER
ISW's August 30 update reports Ukrainian strikes on the Yeysk and Millerovo airfields in Russia, aimed at degrading Russian strike and air defense assets. Geolocated footage and NASA FIRMS heat data corroborated fires at both sites following the strikes.
ISW reports Ukrainian forces conducted a clearing mission with foot-mobile infantry southwest of Zapadne and continued advancing west of Dvorichna near Kupyansk. ISW assesses the advance likely followed a condition-setting effort that suppressed Russian drone capabilities in the area beforehand.
Footage reviewed by ISW shows Ukrainian troops moving through open terrain without apparent Russian interference, which ISW says suggests prior suppression of Russian drone defenses allowed the advance. ISW frames this within a broader pattern of both sides seeking to restore tactical maneuver since 2025.
ISW also reports continued Ukrainian strikes on the Kirishi oil refinery and describes a Ukrainian campaign against Russian marketplaces that Ukrainian intelligence says has sharply raised seller commissions and cut profitability, straining Russian logistics and consumer spending.
OTHER SIGNALS
IRAN | REGIME SUPPRESSES ECONOMIC MESSAGING, ARRESTS PROTEST FIGURES
ISW report of August 28 · carried forward
ISW's August 28 update, carried forward as the latest available Iran report, states that Supreme Leader Mojtaba Khamenei's Telegram account implicitly instructed officials to avoid public statements highlighting Iran's worsening economic conditions. ISW assesses this likely aims to prevent such statements from fueling public frustration. President Pezeshkian nonetheless reiterated the severity of Iran's economic situation shortly afterward, linking it to war, sanctions, and the naval blockade.
The Iranian Intelligence Ministry announced the arrest of 30 alleged leaders and participants of the December-January protest wave, according to the source. ISW assesses the regime may be trying to preemptively disrupt networks capable of renewed mobilization. Separately, the source reports the United States rejected an Iranian-backed Iraqi militia proposal to pause operations for two years instead of disarming, calling it a trick.
TAIWAN | LEGISLATURE FUNDS DRONE BUILDUP, CHINA PROBES ROCKET FORCE GRAFT
ISW report of August 28 · carried forward
ISW's August 28 China and Taiwan Update, carried forward as the latest available report, states Taiwan's Legislative Yuan passed a NT$240 billion six-year budget for unmanned systems procurement and domestic drone industry development. The bill funds coastal attack and reconnaissance drones and unmanned surface vehicles, though Defense Minister Wellington Koo criticized its annual spending cap as a potential obstacle to procurement.
The source also reports China's PLA procurement website solicited corruption reports tied to the PLA Rocket Force by November 30, which ISW assesses indicates Beijing views prior anti-corruption efforts within the service as insufficient. ISW notes this follows years of high-level purges affecting PLA leadership and the Central Military Commission.
KOREA | PYONGYANG SIDELINES SEOUL AS TRUMP EYES KIM MEETING
ISW report of August 26 · carried forward
ISW's August 26 Korean Peninsula Update, carried forward as the latest available report, states North Korea is unlikely to negotiate denuclearization or arms control with the United States. President Trump described his relationship with Kim Jong Un positively and said he expects to meet Kim in 2026, reportedly possibly at the November APEC summit in Shenzhen.
The source reports Kim Yo Jong mocked South Korea as a US puppet state, reinforcing what ISW describes as Pyongyang's Korea passing strategy of engaging Washington while isolating Seoul. South Korean opposition lawmakers separately raised calls for independent nuclear armament amid concerns over reduced joint exercises.
DEFENSEHUB ASSESSMENT
MEDIUM CONFIDENCE: Ukraine's strike tempo against airfields and refineries appears to be strengthening based on repeat hits and geolocated fire evidence, though ISW does not confirm sustained degradation of Russian air defense capacity.
CALL, 30 DAYS: Ukraine will likely continue repeat strikes on the same Russian refineries and airfields through late September. Falsified by ISW reporting a halt or significant reduction in Ukrainian long-range strikes on these facility types within 30 days.
72-HOUR OUTLOOK
UKRAINE: Watch for further Ukrainian strikes on Russian airfields or refineries and additional Kupyansk-area advances reported by ISW.
IRAN: Watch whether Pezeshkian or other officials continue publicly discussing economic conditions despite Mojtaba's office's warning.
TAIWAN: Watch for implementation steps on Taiwan's drone budget and any further PLA Rocket Force corruption disclosures.
KOREA: Watch for any confirmation of a Trump-Kim meeting timeline or further South Korean opposition nuclear armament statements.
