Alas, special interests would not allow it to happen, and now both parties are searching for an enemy to justify military spending that exceeds that of all other developed nations combined.
As Mises writes in Liberalism, a classical liberal makes no distinction between foreign and domestic policy. Strict limits on the power of government to intervene apply in either case. Liberty and empire are incompatible. A government powerful enough to wage aggressive war on foreign peoples will also aggress against its own people.
As the Clinton administration pursues a policy of war in its relations with Iraq and Serbia, and the Congress continues its frenzied hysteria against China and Russia, it is the obligation of every classical liberal, in the interest of liberty, to throw himself into the battle against the warfare state.
The book that has been hailed as the most comprehensive attack on the warfare state to appear in decades is co-published by the Mises Institute and Transaction Publishers. It is John V. Denson's edited volume The Costs of War, now available in a new and expanded 2nd edition.
