A quick little data nugget from the new Harvard Institute of Politics survey of people aged 18 to 29. (We looked at the economics earlier.)
But the very next question added more context. "If the United States needed additional troops to combat the Islamic State," the pollsters asked, "how likely would you be to serve?"
To that question, 85 percent of respondents said they'd probably or definitely not join the military.
In other words, at least 45 percent of people under the age of 30 would like to send troops to fight the Islamic State but wouldn't themselves be willing to go.
This is not a new phenomenon in the post-draft world, to be sure, but it is one that will apparently survive into another generation.
