Most of America's Middle East interventions since 2001 have been justified
Afghanistan- The tailban aided and gave safe haven to terrorist groups who did 9/11 , so the invasion of Afghanistan was totally justified , just as declaring war on Japan after Pearl Harbor was totally justified.
Iraq - This one was unjustified
Libya - Unjustified
Airstrikes against ISIS - totally justified as ISIS is a threat to the US and the world .
Airstrikes against ISIS (in Syria) come with the tiny problem that they're illegal under international law.
And you left out
Somalia - unjustified (except for anti-piracy operations)
Yemen - unjustified
