Day 23: Trump sets a 48-hour clock on Hormuz while Russia’s Spring offensive shatters on Ukrainian defenses.
48 Hours
Trump demands Iran reopen the Strait of Hormuz or face destruction of its energy infrastructure. Iran responds that all US energy assets in the region will be targeted — and threatens desalination plants across the Gulf. The ultimatum follows Iran’s most destructive strike yet on Israel: missiles struck towns near Dimona, wounding 160+, after Israeli air defenses failed to intercept at least two projectiles. A 10-year-old boy is in serious condition.
Oil is up 3.5%. The VIX sits at 26.78. Six fuel ships bound for Australia have been cancelled. The EU is urging members to begin storing winter gas. Day 23 of a war that started with targeted strikes and is now threatening civilian water supplies.
The Lyman Assault
Russia launched its anticipated Spring-Summer offensive against Ukraine’s Fortress Belt — the defensive line anchored by Slovyansk, Kramatorsk, and Kostyantynivka. On March 19, a battalion-sized assault near Lyman: 500+ infantry, 28 armored vehicles, 100+ motorcycles, across seven axes. Ukrainian forces had observed preparations for six weeks.
The result: 405 Russian casualties — 81% of the assault force. Ukrainian forces are now counterattacking: recapturing positions in Chasiv Yar, advancing near Kupyansk, conducting deep strikes on refineries in Saratov and chemical plants in Tolyatti. ISW assesses Russia is unlikely to seize the Fortress Belt in 2026 given unsustainable casualty rates and poorly trained replacements now receiving only one week of basic training.
