ANALYSIS-Growing US push for change in Cuba ties,despite Bush

By Susan Cornwell

WASHINGTON, March 3 (Reuters) - Growing ranks of U.S. politicians, from nearly one-fourth of Congress to a presidential candidate, are urging a review of U.S. policy shunning Cuba, challenging President George W. Bush's view that now is not the time.

The policy has been unpopular for years among some U.S. analysts, who say Fidel Castro's resignation offers a chance to reconsider a hard-line approach that has kept Washington out of Cuba while most of the world is engaged there.

"It's an embargo on American influence, is what it is," said Cuba expert Philip Peters.

"How does it make any sense? We talk to North Korea, we have relations with China, but we won't talk to Cuba," said Wayne Smith, a former U.S. diplomat who was chief of mission at the U.S. interests section in Havana from 1979 to 1982.

Since Castro stepped aside and his brother Raul became Cuban president last month, 24 U.S. senators and 104 members of the House of Representatives have signed letters to Secretary of State Condoleezza Rice seeking a fresh look at Washington's restrictions on trade and travel to the Caribbean island.

Cuba policy has also become an issue in the presidential campaign. Democratic candidate Barack Obama declared that as president he'd be willing to talk with Raul -- an idea quickly denounced by Bush, whose term ends in January.

"I'm not suggesting there's never a time to talk, but I'm suggesting now is not the time," Bush said last week.
