In the international field, we also have examples of the use of non-violent coercion. Thomas Jefferson, during the struggle for the recognition of American neutral rights by Britain and France, attempted to employ the economic weapons of pre-revolutionary days. His embargo upon American commerce and the later variants on that policy, designed to force the belligerents to recognize the American position, actually were more costly to American shippers than were the depredations of the French and the British, so they forced a reversal of American policy. The war against England that followed did not have the support of the shipping interests, whose trade it was supposedly trying to protect. It was more an adventure in American imperialism than it was an attempt to defend neutral rights, so it can hardly be said to have grown out of the issues which led to Jefferson's use of economic sanctions. The whole incident proves that the country which attempts to use this method in international affairs must expect to lose its own trade in the process. The cause must be great indeed before such undramatic losses become acceptable.[51]

The same principle is illustrated in the attempt to impose economic sanctions on Italy in 1935 and 1936. The nations who made a gesture toward using them actually did not want to hinder Italian expansion, or did not want to do so enough to surrender their trade with Italy. The inevitable result was that the sanctions failed.

The success of non-violent coercion is by no means assured in every case. It depends upon (1) the existence of a grievance great enough to justify the suffering that devolves upon the resisters, (2) the dependence of the opposition on the cooperation of the resisters, (3) solidarity among a large enough number of resisters, and (4) in most cases, the favorable reaction of the public not involved in the conflict. When all or most of these factors have been present, non-violent coercion has succeeded in our western society. On other occasions it has failed. But one who remembers the utter defeat of the Austrian socialists who employed arms against Chancellor Dolfuss in 1934 must admit that violent coercion also has its failures.[52]
