Free trade and private investment are commensurable with peaceful, docile nations. Military and monetary deployments are not only anathema to the true sovereign rights of nations but are also explosive ways of enraging belligerent nations while encouraging some to become subservient to the protector. However, it is to be noted that they have not assumed control of the world, they merely have been invited to the upper posts of influence. Since constitutionalists and libertarians do not wish to have an activist governmental foreign affairs apparatus, they generally avoid working in such positions. Thus, those who wish to continue the direction of the world's foreign policy are the only ones willing to work for their own creation.
Free trade is the only option in the free society.
As a matter of fact, to trade freely is a right of free individuals that has been respected since the days of ancient history. Though few ancient civilizations can be called free, one of the reasons cultures blended so swiftly to bring about the global communication we enjoy today is due to the exchange of goods between cultures. As important a medium trade is for cultural exchange, it also is a voluntary compact between two parties. If property ownership is a right originating from man's self-ownership and his attachment of ownership rights to anything he freely accepts or legally acquires, then the exchange of that right in a trade relationship can only be degraded if there is a tariff, or embargo, or sanction. There are sanctions against Iraq which are far more threatening than any bombing campaigns or petty dictators.
