A spokesperson for Iran's Islamic Revolutionary Guard Corps said that any U.S. strike on Iranian infrastructure would be met with a devastating retaliatory response [1].

This escalation heightens the risk of a direct military confrontation between Tehran and Washington. The warning follows claims from Iran that the United States is threatening to target critical infrastructure within the Islamic Republic [1, 5].

The IRGC spokesperson issued the statement in April 2026, signaling a shift from restraint to active threat [1]. The spokesperson targeted the leadership of the United States in the warning, suggesting that previous restraint by Iran would end if infrastructure targets were hit [1].

"If the recent threats by the empty-headed president of the United States to target the infrastructure of the Islamic Republic of Iran … then everything that has so far remained intact due to Iran’s restraint … will be smashed by the iron blows of the powerful armed forces of the IRGC," the spokesperson said [1].

Reports on the conditions for this retaliation vary. Some sources said the response would follow any U.S. strike on Iranian infrastructure [1]. Other reports indicate that the retaliatory response would be triggered by attacks from both the U.S. and Israel on Iranian or regional targets [5].

The IRGC maintains that its armed forces are prepared to deliver a crushing blow to any entity that violates Iranian sovereignty [2, 3]. This rhetoric aligns with a broader pattern of regional tension, where Iran asserts its ability to strike targets beyond its own borders to protect its domestic assets [2].

“"...everything that has so far remained intact due to Iran’s restraint … will be smashed by the iron blows of the powerful armed forces of the IRGC."”

The rhetoric from the IRGC indicates a strategic red line regarding critical infrastructure. By framing the response as 'crushing' and 'devastating,' Tehran is attempting to create a deterrent against U.S. precision strikes. The inclusion of Israel in some reports suggests that Iran views regional security as an interconnected web, where an attack by one Western-aligned power could trigger a wider regional conflict.
