As to why it matters whether Stalin said it or not, what if instead of 'Stalin' it was attributed to Sam G. Smith of Topeka Kansas... Because Sam G. Smith has no political credentials. Attributing this quote to Stalin is simply arrogance or ignorance, unless a source can be cited. It's like attributing a quote to Jefferson or Lincoln that they simply never said, what's the point? what's the motivation? The quote may indeed stand on its own, then why not just let it?

As far as the U.S. is concerned, based on recent elections it appears we have close to a 50 percent split in the U.S.(at least among those who vote)--each half of which is attempting to use "the law" to define justice and enforce it upon the entire populace. If you read the entire book by Bastiat and understand and agree with his premise that "the law" should be limited to the protection of individual people, liberty, and property--you will probably come to the conclusion that the U.S. has perverted the law into far more than it is. In fact, that law has become a tool to be used to force social beliefs on others. Which is better--to have a fairly short-lived war over a period of years and end such perversion or to live perpetually in a society where the law is used as a tool to control? The original American revolutionists believed that war was worth the freedom from this control. 200+ years after their freedom was won--the tyrant is back--irrespective of which side of the political spectrum upon which you find yourself.
