He surly does not.
Only the Congress can declare war; however, MILITARY ACTIONS are something else again! It says so in the Constitution!
In recent history, the president went off on his own in North Korea, Vietnam, Iraq, Afghanistan ( several different times and ways ) and if you want me to go back, farther in American history, I can, but suggest that anyone who disagrees with me, simply look it all up!
We’ve been involved in at least a dozen “wars” where congress was not consulted.
