The War Powers Resolution requires the president to notify Congress within 48 hours of committing armed forces to military action and forbids armed forces from remaining for more than 60 days, with a further 30-day withdrawal period, without congressional authorization for use of military force (AUMF) or a declaration of war by the United States.
Hopefully Trump doesn’t have the power to do any of that regardless of the minor YoY increase in military budget on display here.
