Does "allaying international rivalries" refer to "other schemes" or does it refer to both "Hague Conferences" and "other schemes"?

I know of no parallel to that. The writers, the soldiers, the diplomatists, and the politicians who forewarned us of the War, preached its dangers and its horrors, but they did not tell us that this perilous and horrible tragedy would yet prove to be the birth-throes of a happier world. Nor did the propagandists of Hague Conferences and other schemes for allaying international rivalries warn us that a world-war must precede the attainment of their desires.
