Sir, you portay a very "wishy-washy" view of classical liberalism which is the philosophy of freedom, and from where interventionists stole the term liberal. Classical liberalism ("everything that's peaceful") promotes what you attibute to modern liberalism. It is hard to open holes on a mosquito net so I would focus just in one point of your post: WAR. The big wars you mention have not been initiated by classical liberals, small government types, but by interventionists of all sorts. National Socialism (to name just one case) was not exactly the Libertarian Party. When classical liberals ruled, or to me more precise when the philosophy ruled, there was peace.
