Russia and Belarus conducted their largest joint nuclear exercises in years from May 19 to 21, 2026, with President Vladimir Putin and Belarusian President Alexander Lukashenko monitoring the drills by video link in a first for both leaders. Russian forces delivered nuclear warheads to field storage sites inside Belarus, test-fired a Yars intercontinental ballistic missile and a Zircon hypersonic missile, and mobilised more than 64,000 troops, 200 missile launch platforms, 140 aircraft, and 13 submarines. NATO Secretary General Mark Rutte warned that any use of nuclear weapons would bring a devastating response.
