Former Defense Secretary warns US "locked into an unwinnable war" with Iran; tensions escalate

Tensions between the United States and Iran have sharply escalated throughout July 2026, marked by a series of military strikes from both sides. This ongoing conflict, which officially began in February 2026, intensified after Iran attacked commercial vessels in the Strait of Hormuz, prompting the U.S. Central Command to launch extensive retaliatory operations. Most recently, on July 29, the U.S. carried out a "heavy wave of strikes" against numerous Islamic Revolutionary Guard Corps targets following an attempted Iranian attack on U.S. forces in Jordan. These recent American strikes were reportedly double the intensity and scope of previous operations.

Amidst the escalating military actions, former U.S. Defense Secretary Mark Esper issued a stark warning on July 16, cautioning that the U.S. would not achieve victory in the conflict through aerial bombardment alone. He suggested that a more effective strategy would involve economic pressure on Iran to open the Strait of Hormuz. This sentiment comes as Democrats have criticized congressional Republicans for what they perceive as a failure to challenge President Trump's handling of the conflict, with some senators arguing that Congress has ceded its constitutional authority over declaring war.

Public opinion polls conducted in July 2026 reveal a divided nation, with a majority of Americans believing that engaging in war with Iran was the wrong decision. While most Democrats and independents disapprove of the military action, a significant portion of Republicans continue to support the decision. Despite these internal political divisions, U.S. Defense Secretary Pete Hegseth has maintained that American forces remain ready to escalate pressure, including targeting Iran's energy infrastructure if diplomatic solutions fail.
