Such tolerance is particularly important when it comes to religion. In Tahrir Square, we heard Egyptians from all walks of life chant, "Muslims, Christians, we are one." America will work to see that this spirit prevails -- that all faiths are respected, and that bridges are built among them. In a region that was the birthplace of three world religions, intolerance can lead only to suffering and stagnation. And for this season of change to succeed, Coptic Christians must have the right to worship freely in Cairo, just as Shia must never have their mosques destroyed in Bahrain.
