There are a few things that your post makes me think of, Peter. First, I hadn't thought of the tourist/soldier dynamic in terms of today's recruitment, but I think that is a really interesting point. My friend's husband just decided to re-enlist with the air force after 4 years, even though he has had bad experiences being in Iraq and Qatar, in part because the military offered them the chance for travel - if they spend x number of years in Okinawa, Japan, they were told, they would get their choice of desirable international placements like Spain after that. This seems to intersect Keenan's ideas about the collapse of tourism and war, in that these zones are considered desirable precisely because they are not war zones, but soldiers are still placed there - partially, it seems, as a reward for braving real war zones.
The second thing that your post made me think of in its links to Keenan’s articles was the increasing practice of township tours in
I’m not sure where I’m going with this – I can’t come up with a conclusion of any sort to the questions you raise. So I will just leave it with these connections and try to think further about this strange collapse.
