WASHINGTON: The United States insists it attacked Iran to curb “direct threats” from the Islamic republic, but legal experts say the dangers cited by Washington do not justify war under international law.

US and Israeli forces launched a massive air campaign against Iran on February 28, with Washington saying it aimed to curb nuclear and missile threats from Tehran. Yet the war has also decapitated the country’s government, and President Donald Trump is now demanding “unconditional surrender.”

The White House laid out Washington’s justification for the war during a news conference this week.

“This decision to launch this operation was based on a cumulative effect of various direct threats that Iran posed to the United States of America, and the president’s feeling, based on fact, that Iran does pose (an) imminent and direct threat,” Press Secretary Karoline Leavitt said Wednesday.

She went on to cite Iranian sponsorship of “terrorism,” its ballistic missile program and its alleged efforts to “create nuclear weapons and nuclear bombs.”
