Holding over someone's head the fact that America helped in a War effort to free a country decades before you were even born isn't really a valid argument. They didn't help so we could brag about it 60 years later when people bash America.
I still don't see how knowing the capitol of Pakistan is going to affect my life in any way. Just seems like useless knowledge to me, there are much more useful things to study. Sure you need a fair amount of geography, but you don't really need to know exactly where everything is. Especially countries on the other side of the globe that you never come into contact with. As long as you know the approximate area and have a map when you need one, you'll be fine.
