the tension factor!

With all the tension that is raging all around us all the time one can only wish that the world was amuch quieter place.but that does not seem to be happening anytime soon.especially with Iran increasing the tension levels in the middle east.
thinngs in the sub continent are not that great either.especially with the recent anti china view proposed by the defense department.but the facts do remain that China is building up her military and they seem to be quite aggresive about it.
the defense department siad in not so many words that if China was to attack any country be it Taiwan or India itself,it can mean only one thing -war.and thats all we need right now.why is it so hard for the people to think of peace?
