Are the US and Israel at war with Iran if Congress hasn't declared it?
USA TODAY
The U.S. Constitution gives Congress the sole power to declare war, but since 1973, every president has used the War Powers Act.
The United States and Israel carried out military strikes against Iran on Saturday, Feb. 28 targeting the country's top leaders and plunging the Middle East into a conflict that President Donald Trump said would end a security threat to the U.S. and give Iranians a chance to topple their rulers.
While the U.S. Constitution gives Congress the sole power to declare war, a power last officially exercised in 1942 for World War Two, presidents often act under the War Powers Act of 1973 or their authority as Commander in Chief to engage in military actions without formal Congressional approval.
Every president since Gerald Ford has used the resolution to initiate or justify military actions in conflicts including Vietnam, Yugoslavia, Libya, Iraq and drone strikes in the Middle East.
