Key Thresholds Crossed
First direct U.S.-Iran state exchange since 1979
Crossed: Feb 28, 2026

Hormuz disruption triggers global oil crisis
Crossed: Feb 28, 2026

U.S. Gulf basing arrangements targeted
Crossed: Jul 8, 2026
Iran targeting U.S. military bases in Kuwait and Bahrain escalates direct state-on-state confrontation and risks pulling additional Gulf partner states into the conflict.
