Yes.

Recent presidents have repeatedly ordered military attacks on other countries despite questions over whether congressional approval was needed.
The latest was Republican Donald Trumpβs June 21 bombing of Iranβs nuclear facilities. His administration said he had authority to limit nuclear proliferation.
Trump in 2017 cited national security interests for a missile strike on a Syrian base that was used to launch chemical weapon attacks on Syrian civilians.Β
In 2021, Democrat Joe Biden ordered an airstrike on Iran-backed militia groups in Syria, citing βself-defense.βΒ
In 2011, Democrat Barack Obama ordered βlimitedβ airstrikes on Libya. He said he was trying to protect pro-democracy protesters targeted by Libyan dictator Moammar Gadhafi.Β
The Constitution says only Congress has the power to declare war.
But that provision βhas never been interpreted β by either Congress or the executive branch β to require congressional authorization for every military action that the president could initiate,β a Council on Foreign Relations legal expert wrote.
