Forestal, if you were to look up stop loss, you'd find that Congress created it after Vietnam and that those who join the military agree to it because it's in their enlistment contract:
"In the event of war, my enlistment in the Armed Forces continues until six (6) months after the war ends, unless my enlistment is ended sooner by the President of the United States."
You would also see that the Pentagon under the direction of General Gates is working on minimizing this practice:
Washington Post - Miliary Aims to Cut Back on Stop Loss
From the article:
In an action branded a backdoor draft by some critics, the military over the past several years has held tens of thousands of soldiers, sailors, airmen and Marines on the job and in war zones beyond their retirement dates or enlistment length.
It is a widely disliked practice that the Pentagon, under new Defense Secretary Robert Gates, is trying to figure out how to cut back on.
Gates has ordered that the practice _ known as "stop loss" _ must "be minimized." At the same time, he is looking for ways to decrease the hardship for troops and their families, recruit more people for a larger military and reassess how the active duty and reserves are used.
