So what's the answer?
Lennon had a multitude of suggestions.
"If everyone demanded peace instead of another television set, then there'd be peace."
"If you want peace, you won't get it with violence."
"Say you want a revolution / We better get on right away / Well you get on your feet / And out on the street / Singing power to the people."
And my favorite advice of all: "All you need is love. Love is all you need."
