Aren't We Just Sick and Tired of Wars, People?

In his song "Imagine" (released in 1971), John Lennon mentioned 7 things to be "imagined"

Imagine there's no heaven

Imagine all the people living for today

Imagine there's no countries

And no religion too

Imagine all the people living life in peace

Imagine no possessions

Imagine all the people sharing all the world

I say.. If John Lennon were still alive, he would add another line to the song;

Imagine there's no need for oil and the sun is all we need...

So sick of wars.. So so sick of wars..
