Iran war justified by Tehran's 'aggression' over decades, US legal adviser says

WASHINGTON: The U.S. State Department's top lawyer has argued that President Donald Trump's war with Iran was launched in self-defense and to defend U.S. ally Israel, arguing the bombing campaign was not the start of a new war but the continuation of an ongoing conflict.

State Department Legal Adviser Reed Rubinstein made the arguments in a statement released days before a May 1 deadline for the Trump administration to obtain approval for the war from Congress under the 1973 War Powers Act or move to end it.

The U.S. and Israel began airstrikes on Iran on February 28, killing Iran's Supreme Leader Ayatollah Ali ‌Khamenei and much of the country's ⁠leadership in ⁠the initial attacks. Trump said at the time the strikes, which happened just days after inconclusive talks between U.S. and Iranian negotiators, were aimed at destroying Iranian missiles and annihilating its navy and preventing Tehran from obtaining a nuclear weapon.

Trump also urged Iranians to overthrow their government. Many legal experts say the attacks were unjustified under the United Nations Charter, which states that member states must refrain from using force or the threat of force against other states except when force is authorized by the U.N. Security Council or used in self-defense.

The U.S. was "engaged in this conflict at the request of and in the collective self-defense of its Israeli ally, as well as in the exercise of the United States' own inherent right of self-defense," Rubinstein said, citing what he called "Iran's malign aggression over decades" since the Islamic Revolution of 1979, including attacks by Iranian proxies on U.S. ​forces and Israel, Iranian missile strikes against Israel in 2024 and Tehran's pursuit of nuclear weapons.

"In truth, the United States is ⁠acting well within ‌the recognized contours of international law relating to the use of force and self-defense," he added.

Iran has long denied accusations by Western powers that it is seeking ​to develop nuclear weapons. The statement, ​entitled "Operation Epic Fury and International Law," was posted on the State Department's website on Tuesday but, unlike most of the department's statements, it was not ⁠sent to the media or published on official social media channels.

Iran responded to the U.S. and Israeli attacks by ​launching missiles and drones against U.S. targets, its Middle East neighbors and shipping, snarling the vital Strait of Hormuz waterway. The war, which ​has sparked an energy shock and concerns about wider economic fallout, has been paused since an April 8 ceasefire.

Opinion polls show the war is unpopular with Americans, who have seen the prices of fuel, food and other products jump during the past eight weeks. Reuters/Ipsos poll results released on Friday showed a clear majority of Americans blame Trump for surging gasoline prices, which are weighing on his Republican Party ahead of the midterm elections in November.

LEGAL CONCERNS

More than 100 international law experts published a letter this month saying the initiation of the conflict was "a clear violation" of the U.N. charter. "Despite the Trump administration's varied and sometimes conflicting claims to the contrary, there is no evidence that Iran posed an imminent threat that could ground a self-defense claim," they wrote, citing actions including the bombing of a girls' ‌school that investigators believe was likely a U.S. strike, the killings of political leaders unconnected to the military and threats against Iran's civilian infrastructure.

Rubinstein concluded the campaign that began in late February was "part of an armed conflict with Iran that has been ongoing for years" and said it was unnecessary to assess whether an Iranian attack ​on the U.S. or ​an ally was imminent.

"The U.S. has acted well within ⁠its international law obligations with respect to its use of force since operations began in late February," Rubinstein said. Brian Finucane, a former State Department lawyer now at the International Crisis Group, said in an analysis published by Just Security that Rubinstein's statement was "both legally unpersuasive and analytically confused," adding that "this defective and overly permissive justification risks further eroding legal constraints on the use of force."

Representative Gregory ​Meeks of New York, the top Democrat on the House Foreign Affairs Committee, called it a "late and weak legal justification." In a statement, he said, "The President should comply with domestic and international law and end his war of choice."

Congressional aides said Rubinstein's statement was issued by the Trump administration likely to get ahead of a May 1 deadline to ask Congress to authorize the war. The War Powers Act says the U.S. president must end any ongoing conflict after 60 days unless he obtains that authorization to continue. A president can obtain a 30-day extension if he certifies in writing, to Congress, that the continuing use of armed force is necessary.

Democrats, who are in the minority in both chambers of Congress, have tried repeatedly since the war began to pass resolutions ending the conflict until Trump obtains congressional approval, but almost all Republicans have voted to block them.
