11 April Washington Post commentary - Vietnam's Forgotten Lessons by Richard Cohen.

...We all know the cliche about generals fighting the last war, but in Iraq it is not the tactics that were duplicated -- certainly not compared to the Persian Gulf War -- but the tendency of the military to do what it was told and keep its mouth shut. Shelton, who retired in 2001, cannot be blamed for this and maybe no one but Donald Rumsfeld can, but the fact remains that the United States fought a war many of its military leaders thought was unnecessary, unwise, predicated on false assumptions and incompetently managed. Still, no one really spoke up.

Now, some have -- although from retirement. In recent days, three former senior officers have called for Rumsfeld to be sacked. The most recent is Marine Lt. Gen. Greg Newbold, who does not stop at faulting Rumsfeld but blames himself as well. "I now regret that I did not more openly challenge those who were determined to invade a country whose actions were peripheral to the real threat -- al-Qaeda," he writes in a Time magazine article this month. He joins Maj. Gen. Paul D. Eaton, who commanded the training of Iraqi security forces and who has also called on President Bush to fire Rumsfeld. "President Bush should accept the offer to resign that Mr. Rumsfeld says he has tendered more than once," Eaton wrote in a New York Times op-ed piece.

The third retired general is Anthony Zinni, a four-star Marine with vast experience in the Middle East. (He was Bush's Israeli-Palestinian negotiator for a while.) He goes further than (merely) recommending Rumsfeld's political defenestration. He also strongly suggests that something is broken in the American military, that its priories are misplaced. Too many senior officers put their careers first and candor or honesty second. One who did not, the then-Army chief of staff, Eric K. Shinseki, was rebuked by Rumsfeld and his career essentially ended. After that, the brass knew that the path to promotion was to get with the program. They saluted Rumsfeld and implemented a plan many of them thought was just plain irresponsible...
