ANALYSIS - Clinton star power flickers in diplomatic arena

By Andrew Quinn

WASHINGTON (Reuters) - When Hillary Clinton took the job as President Barack Obama's top diplomat, some analysts said she might be too big for the State Department.

In the public eye for decades as political wife, U.S. first lady, senator and finally presidential candidate, Clinton's career has won her admirers at home and abroad, making her one of the brightest stars in the Obama administration.

But after a turbulent tour of diplomatic trouble spots this week, it is clear that Clinton's star power alone cannot solve some of the world's intractable problems.

"The administration has a host of major problems in the region, running from Pakistan in the east to Israel in the west, yet none of these issues has become a signature issue for her," Jon Alterman, a Middle East specialist at the Center for Strategic and International Studies, said in an email message.

"She did what she had to do over the weekend, but it wasn't entirely clear that her heart was in it."

Clinton had two objectives on her 9-day trip to Pakistan and the Middle East: repair the fraying U.S. relationship with Islamabad, and build support to relaunch peace talks between Israelis and Palestinians.

Neither was a slam dunk, although U.S. officials said hopefully they saw some signs of progress on both fronts after days of Clinton's hectic personal diplomacy.

Asked at a Cairo news conference to weigh the trip's achievements against its disappointments, Clinton herself showed no hint of doubt.
