On the Iranian Border, More Military on the Way, Warm Western Winter

What It Covers

NPR's Up First covers the 22-day US-Israel war in Iran, including troop deployments, a growing Persian Gulf oil crisis affecting 3,000 stranded ships, and a record-dry Western winter threatening water supplies and summer wildfire conditions.

Key Questions Answered

• •Iran civilian toll: Human rights groups estimate between 600 and 1,300 Iranian civilians killed in 22 days of strikes. A near-total communications blackout makes accurate counts impossible, leaving Iranians inside the country in sustained uncertainty about where strikes will fall next.
• •Strait of Hormuz blockade: Iran has effectively shut down the 21-mile-wide strait, stranding roughly 3,000 vessels in the Persian Gulf. The US has only 20 naval ships in the region, and no allied nation has pledged a concrete asset like a warship to reopen it.
• •Oil supply disruption scale: Energy analyst Daniel Yergin of S&P Global identifies this as the largest oil supply disruption in history. Asia bears 80% of the impact, receiving 80% of Gulf oil and 90% of its natural gas through Hormuz, hitting Japan, South Korea, India, and China hardest.
• •Western water crisis timeline: Every river basin in the American West recorded its warmest or second-warmest winter on record. The Federal Bureau of Reclamation projects Lake Powell and Lake Mead could drop to "dead pool" levels — too low to generate hydroelectric power — before year's end.
