Look through the eyes of a seasoned warrior and former chairman of the Joint Chiefs of Staff and you'll understand why President Obama in this year of recession has a better-than-even chance to convince Congress to slow down the Pentagon's expensive pursuit of the Holy Grail of a perfect missile defense.

Why in this new age where terrorists are the big threat should U.S. leaders continue to do so much worrying and spending to combat the comparatively remote possibility that an outlaw state like North Korea would send a nuclear-tipped missile flying into the American homeland?

This was the question posed to me by Army Gen. Hugh Shelton just before he retired as chairman of the Joint Chiefs in 2001 and which he is still asking today.

Shelton told me then and now that a terrorist or outlaw state bent on harming our homeland would be far more likely to do something easier like board a sight-seeing boat that circles Manhattan; go out on deck at a propitious moment; pull out the mortar tube hidden under his coat; set it up quickly and "pop off 10 mortar rounds" filled with poison gas, then "throw the mortar tube overboard; go back in the cabin for a drink."

The mortar shells could be timed to explode over the city and spew out poison gas that could kill hundreds and perhaps thousands on the streets below.

Given the recession and crucial money needs of the U.S. military, especially the Army and Marine Corps, which wore out their equipment in Iraq and Afghanistan, Shelton believes spending so much on an unproved missile defense is a rush to failure.

"Today, as at the beginning of this century, we do not have a proven, effective national missile defense system," Shelton told me last week. "It is embryonic at best and will eventually have to be replaced, upgraded with effective equipment, when available, at great taxpayer expense."

"With today's economic challenges and the growing recapitalization bill facing both the Army and Marine Corps as a result of Iraq and Afghanistan," Shelton continued, "it is time to re-examine the national missile defense program and stop spending exorbitant taxpayer dollars on the fielding of an unproven-ineffective missile defense."

The GAO, in a devastating report issued this month on the nation's missile defense effort, strengthens what Shelton is saying now and what Obama plans to say to Congress.

The new commander in chief intends to urge lawmakers to go along with his cuts in missile defense and "fly before buy" rather than continue to rush little-tested systems to the field. The subtitle of the GAO report will give Obama's fly-before-buy recommendation some lift: "Production and fielding of missile defense components continue with less testing and validation than planned."

GAO's other significant findings in its 104-page report included these: "The Missile Defense Agency has spent about $56 billion and will spend about $50 billion more through 2013 to develop a Ballistic Missile Defense System."

Cost overruns just on individual contracts, not the whole missile defense effort which GAO could not calculate for lack of available figures, are expected to be between $2 billion and $3 billion. "Testing shortfalls have slowed the validation of models and simulations which are needed to assess the system's overall performance. Consequently, the performance of the BMDS as a whole cannot yet be determined."

GAO seems to be saying that even after spending $56 billion on this pursuit of leak-proof missile defenses, with at least another $50 billion to follow, we still don't know whether the United States can stop an incoming bullet with another bullet, with a laser beam, with a flying object or with anything else. At least we knew how to build that bridge to nowhere in Alaska.

Besides the recession, GAO's findings and the coolness of the chiefs of the Army, Navy, Air Force and Marine Corps toward spending so much on a future missile defense when they have here-and-now needs like re-equipping their forces and modernizing them, Obama will have another advantage this year as he tries to rationalize missile defense in his image. That is the absence from Congress of Sen. Ted Stevens, R-Alaska, a long-time defender of the missile defense program from his perch on the Senate Defense Appropriations Subcommittee. Stevens made sure millions of dollars were spent on missile defense in his home state and defended the program. He lost his bid for re-election last year.

Of course there will be members of Congress who will protest any deep cuts in missile defense. They will contend it would be irresponsible to leave the American people naked against incoming missiles, even though they have been virtually naked against the more likely threat of bombers for decades.

And then there are the jobs that would be lost if missile defense were reduced and restructured. Missile defense contractors have lit back fires against the feared cuts. Several insist they really have invented a better mousetrap this time.

If, despite the favorable political winds, Obama fails to convince Congress to cut missile defense this year and adopt his fly-before-buy approach, there is little hope this new commander in chief can tame the military-industrial complex President Dwight Eisenhower warned the nation about in his farewell address in 1961.
