Where sovereign communities are parties, there is no essential difference between a compact, a confederation, and a league. They all equally rest on the plighted faith of the sovereign party. A league, or confederacy, is but a subsisting or continuing treaty. The gentleman's resolutions, then, affirm, in effect, that these twenty-four United States are held together only by a subsisting treaty, resting for its fulfilment and continuance on no inherent power of its own, but on the plighted faith of each State; or, in other words, that our Union is but a league; and, as a consequence from this proposition, they further affirm that, as sovereigns are subject to no superior power, the States must judge, each for itself, of any alleged violation of the league; and if such violation be supposed to have occurred, each may adopt any mode or measure of redress which it shall think proper. Other consequences naturally follow, too, from the main proposition. If a league between sovereign powers have no limitation as to the time of its duration, and contain nothing making it perpetual, it subsists only during the good pleasure of the parties, although no violation be complained of. If, in the opinion of either party, it be violated, such party may say that he will no longer fulfil its obligations on his part, but will consider the whole league or compact at an end, although it might be one of its stipulations that it should be perpetual. Upon this principle, the Congress of the United States, in 1798, declared null and void the treaty of alliance between the United States and France, though it professed to be a perpetual alliance. If the violation of the league be accompanied with serious injuries, the suffering party, being sole judge of his own mode and measure of redress, has a right to indemnify himself by reprisals on the offending members of the league; and reprisals, if the circumstances of the case require it, may be followed by direct, avowed, and public war. The necessary import of the resolution, therefore, is that the United States are connected only by a league; that it is in the good pleasure of every State to decide how long she will choose to remain a member of this league; that any State may determine the extent of her own obligations under it, and accept or reject what shall be decided by the whole; that she may also determine whether her rights have been violated, what is the extent of the injury done her, and what mode and measure of redress her wrongs may make it fit and expedient for her to adopt. The result of the whole is, that any State may secede at pleasure; that any State may resist a law which she herself may choose to say exceeds the power of Congress; and that, as a sovereign power, she may redress her own grievances, by her own arm, at her own discretion. She may make reprisals; she may cruise against the property of other members of the league; she may authorize captures, and make open war.
