Obama: Not hesitant on force to defend interests   WASHINGTON
(AP) -- President Barack Obama says he prefers to use diplomacy
to prevent Iran from obtaining nuclear weapons, but he is making
it clear that he won't "hesitate to use force" when necessary to
defend the U.S. and its interests.  Obama also says in a speech
to a pro-Israel organization that "there is too much loose talk
of war" these days amid concern about a possible pre-emptive
Israeli strike on Iran's nuclear facilities.  The president made
the remarks at the America Israel Public Affairs Committee's
annual policy conference. The address comes one day before a
White House meeting with Israel's prime minister, Benjamin
Netanyahu.  Tehran insists its nuclear program is for peaceful
purposes.
