Is Iraq another Vietnam?

Here's a good take on whether Iraq is another VietNam.

Yet in so many ways, Iraq doesn't look like Vietnam at all. Vietnam was never the central battleground of the Cold War, while Iraq has become the focal point of the war on terrorism. Americans had no reason to feel that their own security was at risk in Vietnam, whereas 9/11 made it clear that the enemy we face today in the Middle East poses a lethal threat here at home as well. The jihadis in Iraq don't have the backing of superpowers; North Vietnam and the Viet Cong were armed to the teeth by China and the Soviet Union. In South Vietnam, the United States was allied to an unpopular and incompetent regime; in Iraq, the United States toppled a brutal tyranny and is trying to nurture a democracy in its place.

But of all the ways in which the Iraq war is not like Vietnam, perhaps the most telling is the attitude of the troops.

"When I was in Vietnam," retired Army Colonel Jack Jacobs, a 1969 Medal of Honor recipient who had just returned from a fact-finding trip to the Sunni Triangle, told NBC News in May, "if you asked anybody what he wanted more than anything else in the world, he'd say: to go home. We asked ... hundreds of soldiers, low-ranking soldiers, in both Afghanistan and Iraq ... the same question. And the response, to a man and a woman, was, 'To kill bad guys.' ... The morale is just over the top — just really, really enthused about what they're doing. And I think the reason is they perceive that they're making progress. Success will do a lot to morale."
