The essentials
US-Iran conflict origin: February 28, 2026 Israeli-American bombing campaign.
The US-Iran conflict originated on February 28, 2026, initiating a sequence of military and diplomatic developments that would define the subsequent months. This date marks the start of an Israeli-American bombing campaign on Iran, establishing the foundational event from which all subsequent escalations and diplomatic efforts emerged.
The initial military action triggered a cascade of responses: retaliatory operations, strategic pauses, failed peace protocols, and renewed escalations across multiple domains including naval operations in the Strait of Hormuz and air defense strikes. The conflict's origins in coordinated bombing operations shaped the intractable nature of later diplomatic attempts, as both sides entered negotiations with entrenched positions rooted in this foundational military engagement.
The February 28 starting point provides essential context for understanding why subsequent ceasefire efforts proved fragile and why underlying disputes persisted despite multiple rounds of negotiation and diplomatic pauses throughout the following months.
