Living in a country where drafting has just been suppressed some months ago, I would want to add a consideration :
After the fall of communism, and without the threat of a major land invasion (and I don’t think a land invasion isn’t the US major concern), the draftees has been considered not only as unuseful, but even as the burden by the military themselves. They couldn’t be used in oversea operations for a lot of reasons, the most important being the impossibility to transport, supply and support more than a certain number of soldiers. And they were diverting ressources.
The military by far preffered to have say, 100 000 professionnal soldiers, and being able to sent oversea half of them with the proper support, than having an army of 250 000 mostly draftees and being unable, by lack of equipment, training or support capacity to sent oversea more than 10 000 of them as it turned up to be the case (it became obvious during the Gulf war).
Once large armor battles in Europe ceased to be expected, draftee units had no role to play anymore. The army began to switch to another organization, with priority given to the ability to perform very different missions.
There has been a lot of reluctance to put an end to drafting. But certainly not from the military. Drafting had been there for more than 200 years, and was…say a traditionnal part of the life of any adult male. There has actually been feelings of nostalgia. More important, a lot of people felt concerned by the fact the army wouldn’t be anymore a citizen’s army but a professionnal army, possibly less reliable and certainly out of touch with the civilians concerns and life.
But the military certainly had no reluctance (apart for some of them the fact that the number of officers and valued commands had to be reduced too). They were asking for this change.
So,my point is : even assuming that the US citizens would accept or even demand a revival of drafting, would the US military be willing to reintroduce it? Would the draftees be of any use for the US army? Is there any foreseeable situation in which the military could need draftees and be able to actually make use of them?
I suppose the number of transmission systems, support units, transports, armored vehicles or whatever else a unit need to operate efficiently is adapted to the current size of the US army. You can’t just give the guys a gun and send them fighting somewhere anymore. In order to have effective fighting draftee units, the US would have to spend a lot more money in material, training,etc…and so the military budget should be drastically augmented. Is such a thing possible, except if they US were actually already involved in a major war (and even in this case, I guess it would be too late to do so)?
