No normal, happy child honestly and spontaneously answers world peace. He/she has to be indoctrinated, taught to say that. Normal children have a very small circle of interest and attention span. Arab tyrants have spent generations blaming the US and Israel for every ill known to mankind, robbing their own people of billions in aid sent by the US and the west. The Palestinian question is a beard. If they'd had a state fifty years ago, bought and paid for by the US, they'd still be blaming Israel and the US for the fact that they don't have enough brains to pour sand in a hole.
Their cult religion has turned them into what they are, which is indescribable in polite company.
P.S. Just for my interest, because it will tell me a lot about your mindset, if you were given the power to make the decision, would you order the aerial bombardment of the nuclear reactor in Iran ?
