Retired U.S. Navy Adm. James Stavridis warned Sunday that Washington should fix its attention on the Suez Canal, saying Iran's behavior and sustained Houthi operations in the Red Sea represent a direct threat to one of the world's most critical shipping lanes.

Stavridis, the former NATO Supreme Allied Commander, made the remarks in a Sunday interview reported by The Hill, calling the waterway the single geographic point Americans should be watching.

Tehran has in recent months escalated public rhetoric about its capacity to disrupt or close the canal, a move that would snarl global trade and cut off rapid U.S. naval transit between the Mediterranean and the Indian Ocean.

Houthi forces, backed by Iran, have conducted repeated strikes on commercial shipping in the Red Sea since late 2023, forcing major carriers to reroute around the Cape of Good Hope and driving up freight costs worldwide.

Stavridis stopped short of predicting imminent action but said the pattern of Iranian signaling demands continuous monitoring by U.S. military and intelligence services.

The Pentagon has not commented publicly on the warning as of Sunday. Congressional defense committee hearings on Red Sea security are scheduled to resume in the coming weeks.
