The position of the Frontier Area is clear in a few respects.[15] In the first place, it is not declining. Communist strength is believed to be growing, by persons of almost all forms of political belief; differences arise only over the rate and probable maxima of that growth. The Communist strength in the Northwest is far less than it was in South Central China seven years ago, but much of that loss of power has been compensated for by increased relations with sympathetic guerrillas. Secondly, the Communist area is strategically poorly located. The land itself is poor; the adjacent large cities are completely under Nationalist control; and the general military-political locale is something like northern Arkansas in the United States. This explains the willingness of the Nationalist commanders to avoid friction with the Communists, and the positive zest with which they suggest further consolidation of Communist forces around the one center at Yenan. It soothes the impatience of Communists who wish unrestricted rights of agitation, organization, and propaganda throughout the country. Although the Communists make little visible headway against the Japanese in the great urban slums of the coast, they are anxious to obtain freer access to city workers. Thirdly, the Communist area displays no structural peculiarities of government. Its profound difference from the rest of Free China is not a difference in institutional forms, but in the forces operating behind and through those forms. The Chinese Communists have achieved very considerable success in working within the legal limits of another state philosophy, and have done it with a minimum of violence; this augurs well for the perpetual continuation of the truce. Their practical accomplishments are extensive and novel; their leadership, brilliant; that their government should be so orthodox in form is all the more significant. By remaining within orthodox limits they challenge the National Government on common ground; the gain is theirs and China's. [Footnote 15: Since the author has neither extensive acquaintance with Chinese Communists, nor has visited Yenan, he offers these conclusions more tentatively than he would others, concerning the Kuomintang.] GUERRILLA GOVERNMENTS
