WASHINGTON (AP) — In his inaugural address, President Barack Obama signaled conciliation to America’s foes by using the metaphor of an outstretched hand to an unclenched fist. Already, there are signs that some of those foes were listening, sensing an opening for improved relations after eight combative years under President George W. Bush. Fidel Castro is said to like the new American leader, and North Korea and Iran both sounded open to new ideas to defuse nuclear-tinged tensions. Unclear is what they will demand in return from the untested American statesman, and whether they will agree to the compromises the U.S. is likely to insist on in exchange for warmer relations.
