What war was John Lennon protesting against in his bed in for peace with Yoko Ono in 1969?

Also, how many album's did John have with Yoko, and how many solo album's did he have?

I'm doing a report on him for history fair.
Update: Yes, the themes is "The individual in history: actions and legacies." I'm making his bed-in for peace the action.
