More than one-third of nearly 3,900 former soldiers mobilized under a special wartime program have resisted their call-ups. The Army National Guard fell nearly 10 percent short of its 2004 recruiting goal of 56,000 enlistees. The Army, concerned about recruiting, has eased some standards.

Just months ago, Pentagon officials suggested that a new draft could be avoided if recruitment and retention numbers stayed high. But as fighting in Iraq escalates, signs are growing that those numbers may not be adequate in the coming years. Thus, the new talk about a draft.
