A U.S. Senator from Iowa is hopeful President Barack Obama's call for a peace accord with the Muslim world is a success. Republican Chuck Grassley says it's a relationship that's been strained for far too long. While Grassley, and other U-S leaders are hopeful Obama's message spawns more dialog, Al-Jazeera reports mixed reactions from the Arab World. Grassley says any amount of insight the east and west can give each other is a step in the right direction.
