UPDATE 1-Ryan a foreign policy question in a campaign about economy

WASHINGTON, Aug 11 (Reuters) - One of the first things

Congressman Paul Ryan said on Saturday when accepting the role

of Mitt Romney's vice presidential running mate was that even

though he was in Congress he had "never really left" his

hometown of Janesville, Wisconsin in the American Midwest.

Ryan's focus on domestic issues and his reputation as a

rather wonky budget hawk confirm that Romney sees the November

contest with President Barack Obama as a referendum over the

U.S. economy and the size of the federal budget.

Still, although U.S. voters overwhelmingly cite economic

issues as their main concern, they also want reassurance that

their leaders can execute the role of commander-in-chief.

Introducing Ryan on Saturday, Romney said his new running

mate was ready. But Democrats are already aiming at what they

say is a dearth of national security experience on the

Republican ticket.

"I think his (Ryan's) experience as a vice presidential

candidate is thin; or for a future president and

commander-in-chief, it's virtually absent," said Tim Roemer, a

former congressman, former ambassador to India and member of the

commission that reported on the circumstances surrounding the

Sept. 11 attacks on the United States in 2001.

Obama had little foreign policy experience when he ran for

president in 2008 as Illinois' junior senator. He chose to

balance that by tapping Senator Joe Biden, who had a long

history of international experience and contacts, as his vice

president.

None of the four men running for the two highest offices in

the land are military veterans.

Romney campaign officials contend that Ryan does bring

experience in the foreign policy department, particularly when

it comes to dealing with the defense budget.

"This election is going to be about which candidate has the

right vision for growing the economy and balancing our budget,

but Governor Romney chose Congressman Ryan first and foremost

because he's ready on day one to step in as commander-in-chief

should he need to assume that responsibility," said Ryan

spokesman Brendan Buck.

Romney and Ryan "share the view that America's leadership

position in the world is based on a robust national defense,

strengthened relationships with our allies and a philosophy of

peace through strength," Buck said.

In a speech last year, Ryan said U.S. fiscal policy and its

foreign policy were on a collision course. "If we fail to put

our budget on a sustainable path, then we are choosing decline

as a world power," he told the Alexander Hamilton Society in

Washington.

GENERIC REPUBLICAN?

Even as he has championed huge cuts in government spending,

Ryan has been protective of the Pentagon's budget, those in the

defense community say.

"Paul Ryan understands how important it is to get our fiscal

house in order, but also that short-sighted, budget-driven

defense strategies are not good for our defense," said

Representative Howard McKeon, the Republican chairman of the

House Armed Services Committee.

He said Ryan, as chairman of the House Budget Committee,

worked to put billions of extra money into defense by finding

cuts in other areas in the budget that the Republican-run House

of Representatives approved this year.

"We had more in defense than the president asked for,"

McKeon said in a telephone interview.

What is known of Ryan's position on other national security

issues suggests that he is in the mainstream of Republican

conservatism.

How his choice will affect serious frictions within the

Romney campaign between foreign policy hard-liners and more

centrist advisers is unclear. Romney's rhetoric has tended to

reflect the hard-liners' views.

"My sense is that Ryan is just a generic Republican on

foreign policy," said Larry Sabato, director of the University

of Virginia Center for Politics.

"Ryan will have to be tutored in this subject prior to his

debate with Biden ... Biden will be loaded for bear in his own

area," Sabato said.

Ryan's website suggests he is in the Republican mainstream

when it comes to the war in Afghanistan. He offers no great

enthusiasm for the war, but does express concern that the pace

of the pullout of U.S. troops under Obama "has the potential to

pose security threats to soldiers" that stay behind.

Ryan's position as a strong supporter of Israel aligns him

with the majority of both parties in Congress. He does not

appear to have said a lot about the conflict in Syria, where

Obama's policy has sharply limited U.S. involvement.

Ryan's constant emphasis on fiscal soundness could play well

on the international stage, said Tom Donnelly, the director of

defense studies at the American Enterprise Institute think-tank

in Washington.

"There is one thing the world really wants to know about the

United States - will we get the government's financial house in

order?" Donnelly said.
