It should come as no surprise that an archconservative Web site is questioning whether Rep. John Murtha, the Pennsylvania Democrat who has been critical of the war in Iraq, deserved the combat awards he received in Vietnam.

After all, in recent years extremist Republican operatives have inverted a longstanding principle: that our combat veterans be accorded a place of honor in political circles.

This trend began with the ugly insinuations leveled at Sen. John McCain during the 2000 Republican primaries and continued with the slurs against Sen. Max Cleland and Sen. John Kerry, and now Murtha.

Military people past and present have good reason to wonder if the current administration truly values their service beyond its immediate effect on its battlefield of choice.

The casting of suspicion and doubt about the actions of veterans who have run against President Bush or opposed his policies has been a constant theme of his career. This pattern of denigrating the service of those with whom they disagree risks cheapening the public's appreciation of what it means to serve, and in the long term may hurt the Republicans themselves.

Not unlike the Clinton "triangulation" strategy, the approach has been to attack an opponent's greatest perceived strength in order to diminish his overall credibility. To no one's surprise, surrogates carry out the attacks, leaving Bush and other Republican leaders to benefit from the results while publicly distancing themselves from the actual remarks.

During the 2000 primary season, McCain's life-defining experiences as a prisoner of war in Vietnam were diminished through whispers that he was too scarred by those years to handle the emotional burdens of the presidency.

The wide admiration that Cleland gained from building a career despite losing three limbs in Vietnam brought on the smug non sequitur from critics that he had been injured in an accident and not by enemy fire.

Kerry's voluntary combat duty was systematically diminished by the well-financed Swift Boat Veterans for Truth in a highly successful effort to insulate a president who avoided having to go to war.

And now comes Murtha. The administration tried a number of times to derail the congressman's criticism of the Iraq war, including a largely ineffective effort to get senior military officials to publicly rebuke him (Gen. Peter Pace, chairman of the Joint Chiefs, was the only one to do the administration's bidding there).

Now the Cybercast News Service, a supposedly independent organization with deep ties to the Republican Party, has dusted off the Swift Boat Veterans playbook, questioning whether Murtha deserved his two Purple Hearts.

The article also implied that Murtha did not deserve the Bronze Star he received, and that the combat-distinguishing "V" on it was questionable. It then called on Murtha to open up his military records.

Cybercast News Service is run by David Thibault, who formerly worked as the senior producer for "Rising Tide," the televised weekly news magazine produced by the Republican National Committee. One of the authors of the Murtha article was Marc Morano, a long-time writer and producer for Rush Limbaugh.

The accusations against Murtha were very old news, principally coming from defeated political rivals. Aligned against their charges are an official letter from Marine Corps Headquarters written nearly 40 years ago affirming Murtha's eligibility for his Purple Hearts — "you are entitled to the Purple Heart and a Gold Star in lieu of a second Purple Heart for wounds received in action" — and the strict tradition of the Marine Corps regarding awards.

While in other services lower-level commanders have frequently had authority to issue prestigious awards, in the Marines, Murtha's Vietnam Bronze Star would have required the approval of four different awards boards.

The Bush administration's failure to support those who have served goes beyond the smearing of these political opponents. One of the most regrettable examples comes, oddly enough, from modern-day Vietnam.

The government-run War Remnants Museum, a popular tourist site in downtown Ho Chi Minh City, includes an extensive section on "American atrocities." The largest display is devoted to Bob Kerrey, a former U.S. senator and governor of Nebraska, recipient of the Medal of Honor and member of the 9/11 commission.

In the display, Kerrey is flatly labeled a war criminal by the Vietnamese government, and the accompanying text gives a thoroughly propagandized version of an incident that resulted in civilian deaths during his time in Vietnam. This display has been up for more than two years.

One finds it hard to imagine another example in which a foreign government has been allowed to so characterize the service of a distinguished American with no hint of a diplomatic protest.

The political tactic of playing up the soldiers on the battlefield while tearing down the reputations of veterans who oppose them could eventually cost the Republicans dearly. It may be one reason that a preponderance of the Iraq war veterans who thus far have decided to run for office are doing so as Democrats.

A young American now serving in Iraq might rightly wonder whether his or her service will be deliberately misconstrued 20 years from now, in the next rendition of politically motivated spinmeisters who never had the courage to step forward and put their own lives on the line.

Rudyard Kipling summed up this syndrome quite neatly more than a century ago, writing about the frequent hypocrisy directed at the British soldiers of his day:

An' it's Tommy this, an' Tommy that, an' anything you please;

An' Tommy ain't a bloomin' fool — you bet that Tommy sees!

James Webb, a secretary of the Navy in the Reagan administration, was a Marine platoon and company commander in Vietnam.
