This Sunday, September 21, the world celebrates the International Day of Peace. This year, the United Nations is observing the day with a timely call to action: Act Now for a Peaceful World. This year’s International Day of Peace comes as militarism is surging in the United States and governments around the world are spending record sums on their militaries. On this International Day of Peace, join people around the globe in acting for peace by urging your members of Congress to invest in aid, not more bombs.
