I think what lots of people are aiming for here is compulsory boot camp and the option to go into service. That way you get people's act together and you still maintain an all volunteer military.
Another thing about some limited compulsory service is that it doesn't put a divide between the people and the military like a lot of professional armies do. Often this is cased because these people who never have served have some strange idea that their military is going to take over their country and are going to make their lives completely miserable. Basically the only glimpses of the military they get is when something goes straight to hell and it makes the newspaper.
You have limited conscription? Then this tends to go away, because they know what it's like.
I know for quite sure that Belgium is pretty serious with this problem now that conscription has gone out the door. I think also wtih the younger generation, the US falls into this category of military hating as well. Places like Israel or Korea who have manditory service don't suffer from this civilian-military divide, while both maintain pretty good armies.
