Among the huge amount of literature on the future war and its nature, published in recent years in bourgeois countries and overwhelmingly purely fantastic and of little value, the book of the Polish general Sikorsky, published in 1934, deserves the undoubted attention of our reader. General Sikorski is one of the prominent political figures in bourgeois Poland. He belongs to the group of its leading circles that advocates the strengthening of the Franco-Polish alliance, given and foreseeing the threat posed to the continued existence of an independent Polish bourgeois republic by the rabid weapons of fascist Germany.
