Ron Paul is often chided by his Republican opponents for his extreme views on American foreign policy.  His calls for ending all foreign wars and shutting hundreds of military bases across the globe have drawn howls from his GOP rivals, who have labeled the moves irresponsible and naïve.

His campaign pledge of cutting all foreign aid and withdrawing U.S. participation in the World Trade Organization and the United Nations has been at odds with even the most conservative members of his own party.

Yet as voting day in Iowa and New Hampshire draws near, Paul, the Congressman from Texas, is finding support for his non-interventionist positions from a growing number of foreign policy experts.

“He’s attacking our rich lazy friends, why is that not more popular,” said  Harvey Sapolsky, emeritus professor of public policy and organization at MIT. He backs Paul’s calls for reducing America’s military budget, arguing that much of it is used to defend wealthy nations’ security.

A huge, Cold War-era global presence — with hundreds of overseas military bases — isn’t necessary, now that the Soviet threat is over and the collapse of communism, Sapolsky said.

“It’s not in America’s interest,” said Sapolsky, who added that despite the drumbeat in the media over the fear of terrorism, America is the safest it has ever been in its history.

Christopher Preble, vice president for defense and foreign policy studies at the Cato Institute, is also another foreign policy expert who agrees that the United States is extraordinarily secure due to its geography and nuclear weapons, and doesn’t need a huge global presence.

He also argued that the United States’ military is being used in overseas conflicts with little or no national interest, specifically pointing to the U.S. invasion of Iraq.

Preble gave Paul credit for being one of the few outspoken critics of the 2003 invasion of Iraq.

For sure America’s attitudes toward the war has changed and popular opinion seems to be on his side.

It’s evident at most of his campaign stops, where Paul’s calls for the troops to return home are met with thunderous applause and the occasional standing ovation.

But not all of Paul’s foreign policy positions have gone over well.

Paul has often said that America encourages terror by stationing troops worldwide.

“That’s irresponsible,” former Pennsylvania Sen. Rick Santorum said. “A future president of the United State should not be parroting what Osama Bin Laden said on 9/11.”

Santorum, who is among Paul’s  rivals for the GOP presidential nomination, challenged him at a recent debate, to explain his view that American overseas domination caused the Sept. 11 attacks.

Paul’s answer received a hostile response from the audience and even a few boos.

Paul’s view that a withdrawal of U.S. troops would decrease the incentive for terrorists to attack the United States g ot him into trouble with a Concord, N.H., voter earlier this year, who questioned his sanity.

“Anyone who thinks that is off their rocker,” she said.

“He’s easily dismissed as a crank,” said Sapolsky, who says Paul has good ideas but can be an inarticulate messenger.

Like most aspects of running a national political campaign, style often outweighs substance and both Sapolsky and Preble said that Paul is neither a great orator nor does he break down large global situations well.

But despite his shortcomings, Sapolsky does give Paul credit for speaking his mind.

“A lot of people won’t say come home,” Sapolsky said. “But Ron Paul does and that’s great.”
