I think one aspect that the author does not acknowledge is - draft Vs volunteer.
The protests against the Vietnam war began in earnest when Johnston got rid of most of the deferments - the middle and upper class were now in jeopardy of getting drafted; they were also people in position of authority - journalists, politicians, moneyed. Also, the health care for the troops has improved and kept the deaths down - if they were higher there might be more protests.
So if we really want to change the threshold for war we should bring back the draft. "civic obligation" might mean "draft".
"The responsibility facing the American people is clear. They need to reclaim ownership of their army. They need to give their soldiers respite, by insisting that Washington abandon its de facto policy of perpetual war. Or, alternatively, the United States should become a nation truly "at" war, with all that implies in terms of civic obligation, fiscal policies and domestic priorities. Should the people choose neither course -- and thereby subject their troops to continuing abuse -- the damage to the army and to American democracy will be severe. "
I think the author is being disingenuous here. There are a huge advantage of a professional army vs a draft army. Among the most important is significantly lower casualties not only for our troops but for civilians. I don't want to minimize the sacrifices that young men and woman and their families on their multiple deployments to lousy places.
However, a little perspective is in order, roughly speaking about 2 soldiers a day have died in our 9 year 'war on terror' and about 10 times than number wounded. Military service is inherently dangerous and even in peacetime a fair number are killed and injured. More over many of these young man, are adrenaline junkies, and if they were not in the military they'd be riding motorcycles, hang gliding, mountain climbing, sreet drag racing and other dangerous things young guys do. In addition, quite a few would be involved in gangs back home where there chance of death or injury are even greater than in the military.
But 2 a day is not a huge number compared in other activities (about the same a bike riding) and is positively small compared to other wars. 60 years ago this month the Korean War started more than 36,000 US serviceman died, and their lasting legacy is 25 million South Korean they defended have now grown to almost 50 million. Most importantly they have been spared the nightmare of living under Kim il-Sung and his equally nutty son's regime.
Now the Korean war is vastly different than wars in Afghanistan and Iraq, but I can't help thinking I'd much rather America fight a 9 years war that defends the citizens of two countries against awfully regimes and cost 6,000 soldiers than a 3 year war that cost 36,000.
One thing that hasn't changed is the value of veteran soldiers. For thousands of years professional armies with veteran soldiers have been able to defeat armies of conscripts and inflict causalities many times there own. Movies, and books of draft wars of WWII, Korea, and Vietnam are filled with stories of replacement draftees being assigned to a unit in combat and killed the next day. Even more dangerous are the 90 day wonder officer who by virtue of their college degree are given command of a platoon and manage to kill both their men and themselves by their inexperienced. Bringing back the draft means more body bags, which is why no military leaders are calling for it.
Just as importantly, I question if a drafted army can ever be successful in winning a counter-insurgency war. A draftee in Vietnam with 36 days 8 hours left in country, would think he saw gunfire at house. He would order an air strike a few minutes later the house would be obliterated. Once the house was gone his problem was solved. It really didn't matter if the house had Viet Cong, or South Vietnamese villager and the killing the latter may have turned their two brothers and an uncle in enemies. In contrast, a professional soldier in Afghanistan would have a different approach. He might also have 36 days left on deployment, but odds are this is is 2nd or 3rd deployment and he has four year commitment ahead of him. This gives him a much better chance of appreciating that it is really important to avoid killing innocent Afghanistan citizens. Before calling in the airstrike, he'd consult with his squad and they may conclude that perhaps the light they saw was actually a lantern and not a gunshot. He knows that he screws up that some other unit maybe bare the consequences, so they take the time to investigate. He knows that he may be coming back if not to this specific place than to one like it. Sure investigating the house is more risky than ordering an air strike, but that is what being a professional is about.
