No one is justifying war and aggressiveness. I am just saying Its all natural or nature define that the people who has power will definitely be more aggressive than other. Other are not so called aggressive in your term don’t have enough power to do so. If they have power, they will damage more than US does. Yes we can raise voice against it and minimize the damage.
There will never be country or person who mind their own business. People are selfish and they will do whatever to be dominant, Its human nature and that applies to country as well .Atleast i am living in the country where i can raise the voice against such issue. I am looking this issue with different views. i hope  i am able to clarify my view.
