Trade and a question

...it makes no sense to attack a good customer, one who buys as much of our products as he can use and pays his bills regularly.  Perhaps the removal of trade restrictions throughout the world would do more for the cause of universal peace than can any political union of peoples separated by trade barriers; indeed, an there be a viable political union while these barriers exist?  And, if freedom of trade were the universal practice, would a political union be necessary?

 Frank Chodorov (1959, The Rise & Fall of Society)
