I beg to differ about conscription being key, while it is important it can also be a plague and a burden to heavy for many armies and countries. The US uses a smaller military that is arguably the best trained in the world (When I say arguably I really mean that we barely nudge out the UK, Russia, Germany, and France for the best trained.) where as other countries, most notable the Soviet Union, were over burdened by the costs of conscription and it eventually resulted in the collapse of that country. (While other factors were also involved with the demise of the USSR I personally feel that to high of military costs were to blame, you can not spend that much money on the military in a true communist system, if anything they should spend no money, since most of the money would need to go to social welfare programs which also over burden the system and encourage people to be lazy, not meeting their true potential.) Israel however is a prime example of a successful draft (some of you may be getting sick of me saying this, well to bad.) they are always under constant threat of invasion and need to keep a large army on hand to thwart any invasion, sometimes that requires them to go on the offensive, their are 7 arab countries, only one Jewish state, the Arabs can take a hit and keep going, the Israelites on the other hand have nowhere to fall back to, except the US as many of the neo-Nazis will tell you.
