There is plenty of precedent for use of US military in recent history:
The Iran hostage rescue attempt (1980)
Military exercises in Honduras (1983)
U.S. marines in a multinational force in Lebanon (1982–1983)
Invasion of Grenada (1983)
Bombing of Libya (1986)
Invasion of Panama (1989)
No-fly zone post Gulf War (1991)
Humanitarian mission to Somalia (1992–1994), and
Bombing of Kosovo (1999)
In all of these cases, members of Congress have complained that the president had not fully complied with the War Powers Resolution.
