The differences in religion have precipitated many European struggles, but for more than a century the countries have been forced to assume an attitude of tolerance, so that churches other than those established by the State have thrived; But just what influence religions may have had in the various incidents of the war it is difficult to determine. The outstanding fact is that but for the arrogant, militaristic policy of Imperial Germany, the differences between nations might have been settled, and almost indescribable horrors of the war would never have been experienced. CHAPTER V. WHY AMERICA ENTERED THE WAR. THE IRON HAND OF PRUSSIANISM--THE ARROGANT HOHENZOLLERN ATTITUDE--SECRETARY LANE TELLS WHY WE FIGHT--BROKEN PLEDGES--LAWS VIOLATED--PRUSSIANISM THE CHILD OF BARBARITY--GERMANY'S PLANS FOR A WORLD EMPIRE. Not merely to prevent Germany from opening avenues of commerce to the seas nor to throttle the ambitions of the Kaiser was America drawn into the vortex of war with France, England, Russia, Belgium, Italy and other nations; but that the iron hand of Prussianism, as exemplified in the conduct of the German Government, might be lifted from the shoulders of men, and the world given that measure of peace and security which modern civilization demands. Germany by her ruthless submarine warfare brought desolation to many American homes. She sank without a pang of conscience the great transatlantic steamship Lusitania, and, while pretending friendship for the United States and pleading no intent to disregard American rights, broke her own pledges and repeated her overt acts, ignoring international law and the rights of all neutrals at sea. She began her outlawry by the invasion of Belgium, which was followed by conduct on the part of the German forces which clearly marked them descendants of the "wolf tribes" of feudal days, fighting with the motto before them of, "To the victor belong the spoils." But all of Germany's diabolical acts involving the peace and security of America and American citizens might have been the subject of international adjudication but for the arrogance of the ruling forces of the Teutons. In a broad sense, Prussianism is credited with responsibility for the devastating war and for the policy which drew America into the conflict. The country, led by President Woodrow Wilson, who temporized to an extent that for a time made him the subject of bitter criticism, found that war was being forced upon it by an autocratic and ambitious German Government--that of the Hohenzollern dynasty--which possessed an insane ambition to dominate the earth, leaving to America no alternative but to borrow the piratical terrorism of Imperialistic Germany, with temporary abandonment of its own constitutional free government, and join the Allies to defend it.
