As an unpopular, ill-planned war in Iraq grinds on inconclusively, it can be a bleak time to be a veteran.

Recent surveys have painted an appalling picture. Almost half a million of the nation’s 24 million veterans were homeless at some point during 2006, and while only a few hundred from Iraq or Afghanistan have turned up homeless so far, aid groups are bracing themselves for a tsunamilike upsurge in coming years.

Tens of thousands of reservists and National Guard troops, whose jobs were supposedly protected while they were at war, were denied prompt re-employment upon their return or else lost seniority, pay and other benefits. Some 1.8 million veterans were unable to get care in veterans’ facilities in 2004 and lacked health insurance to pay for care elsewhere. Meanwhile, veterans seeking disability payments faced huge backlogs and inordinate delays in getting claims and appeals processed.
