Because it is an inherent right of nations - the very core of a nation's national sovereignty - to have the ability to refrain from conflict. A nation should not have to go to war (or withstand a violation of its sovereignty by another nation) if it's not in its interest. So one day, if Svornost is in a region where conflict threatens all nations in the vicinity, it won't have to participate if it's not in it's interest. This proposal carries with it no negative consequences, assuming one believes in civil behavior by all nations.
