You seriously have to have a look at current USA foreign (and domestic) policy. I know how bad British foreign policy is and can be, maybe you should do a little reading up aswell!
And once again we are not blaming the USA for everything wrong in the world, and once again by USA we're meaning the government.
But we are not making it up that the world considers the USA to be the biggest threat to world peace. There have been countless polls about it. Even a CNN poll in Jan 75% considered USA the biggest threat to world peace. You should be bothered that your government is putting you in this position.
But yes you are right, spot on, in fact about the individual aswell as the collective being the key - that peace comes through inner peace.
'Be the change you want to see in the world' as a philosopher once said.
Also, your last sentance is outrageous! You don't appear to have much faith in the human race with a statement like that! The solution is not to get rid of man - we are here for a reason ('for everything a reason' as one Manc once said) and are here for a reason as much as any other creature.
Positives create positive reactions all over the world
Peace, butterflies and positive vibes
