Different era. Things have changed, in those wars most Americans where proud Americans, now the country suffers from euro induced self hate. No thanks on the draft, I don't want my sons butts covered by some slacker who has no sense of country or pride. Besides a forced military will just expand our reach beyond where we should be involved, diminishes self worth to those enlistees and officers and creates a drone mentality.
I agree that those inclined to serve should serve in some capacity, but one cannot serve effectively while shackled.
What we need is more pride in our country to inspire the young to want to serve, unfortunately our leaders whose job it is to inspire no longer seem capable of doing so.
