The author discusses the self-help meuupes of retorsion, reprisal, and intervention, as they relate to international law. His analysis includes the application of theee meuwes in %oh contemporary orises as the Dominican Republic, Southern Rhodesia, and Vietnam. The author conclz~des that the world community is not yet ~eady for a "force monopoly" by the United Nations and that, meanwhile, individual state8 should exercise power in accordance with established international law and the ideals expressed in the United Nations Charter. I. INTRODUCTION
International law is a discipline conceived to bring order to the relationships of a number of states asserting certain rights. Indicative of these rights is the expression of Chief Justice Marshall: "The world [is] composed of distinct sovereignties, possessing equal rights and equal independence. . . .I" It might be said that these rights and their reciprocal obligations are given credence by states applying standards and rules which are designed to define and implement the rights and obligations.
As states emerged and the international community developed, it became apparent that the absence of central authority for this community resulted in ad hoc accommodations amongst the states which depended as much upon relative physical capacities of the states involved as upon any theory of sovereign equality. But even in such a loosely knit society, where resort

to self-help measured of violence could not be discounted, if an interest ws.s deemed important enough, a lexicon grew up, categorizing and setting legal frameworks for testing the proprietp of a variety of coercive measure8 which did not amount to the ultimate measure of war. Although var itself was a measure arailable to states,' it was useful to recognize and employ measures of less generalized effect when limited ends were sought.'

Although the United Nations Charter restricts the use or threat of force by states," it is useful to examine the practice of states prior to that treaty and relate the pnor practice to current practice. Far, while the purposes of the United Sations Organization are manifestly laudible, its effectireness in settling international disputes or assisting in such settlement has been less than ideal.'

existing criteria for justifying forceful action, albeit they now feel more compunction to relate their action to self-defense as that concept is interpreted under article 51 of the United Nations Charter.'
Self-help measures have generally been categorized as retorsion, reprisals, intervention, and self-defense.' These categories are a useful device far orderly discussion of this ares of international law. But it must be borne in mind that there is no intent to imply that the categories are mutually exclusive. However, as will be seen later, retorsion and reprisal may be considered mutually exclusive in that bana fide retorsions are a& within the competence of the state regardless of provwation, whereas reprisals depend for their justification upon their being in response to an illegal act of another state.'
It is important to realize that in the jurisprudence of international law, terminology is sometimes employed simply for its descriptive value without regard to a precise legal definition. So, we find the terms "boycott" and "embargo" in a variety of situations, and we cannot rely on the use of the term as indicative of legal ramifications.
"Boycott" is a term applied in municipal as well as international contexts as a label for a practiced refusal to do business. The United States bans against imports from Cuba and Red China are Instances of boycott which need not be justified as either retorsions or reprisals, since the United States is not obligated by treaty or otherwise to allow imports from those sources. Some boycotts must, however, depend upon the conditians of reprisal for justification, as will be seen later,
"Embargo" is a term applied to many situations which will be discussed within the general heading of reprisals. Sot ail of

This failure eves the Arsbr the right to search for other meand to defend themselves against constant threats and repeated insults.''
the applications of the tern have reference to reprisal. The underlying circumstances must be discovered to understand the sense of the term in each instance.
Aside from any limitations imposed by the United Nations Charter, there are, in a world of sovereigm states, a multitude of actions within the legal competence of states. >Ian>- of these actio- may be considered discoui-reous or unfam to other states, yet nonetheless amongst the prerogatives of the acting state Thus, states have exacted exorbitant tariffs on the impartation of certain products, or even prohibited importation of the products of particular states, regulated immigration on a basic discriminatory against nationals of particular states, or refused to allow ships of a particular state access to ports.
If no treaty violations are involved in the foregoine actions. they cannot be said to be illegal:' They do, however, tend to introduce discord in international relations even thouph their purpose may be simply to enhance some internal program, the effect on the other state being at mast an incidental factor in plans of the acting state. If a state considers itself sufficiently abused by such conduct, it may retaliate by some measure equally within its prerogatives. Such responses are retorsions. Although retorsions need not be in kind, there are examples of retorsions strikingly similar to the provocation, such as the Act of 18 April 1818,"

STATUS OF RETORSION IN COMTEMPORARY IA'TERhrATIONAL LAW
As retorsion is by no means a friendly method of intematianal relations, certain provisions of the United Sations Charter must be considered in determining the availability of re-torsion in modern times.
