Was John Lennon right?  

I hope so.

Every Christmas I sing:

And so this is christmas and what have you done
Another year over a new one just begun
And so this is Christmas I hope you have fun
The near and the dear one's the old and the young
A very merry Christmas and a happy new year
Let's hope it's a good one without any fear
And so this is Christmas (War is over)for weak and for strong
For rich and the poor ones the road is so long
And so happy Christmas (War is over) for black and for white
for yellow and red ones let's stop all the fight

I wish this came true.... maybe one Christmas...
