Vietnam vol.2, it seems like from y'all old geezers (I mean it affectionately).
Perhaps Breacher is right and we'll learn our lesson for, say, another decade or two. I don't think we'll last that long, but hey, what do I know? I'm a skeptic.
I live in a military town and many of my high school classmates are now serving, especially the ones I know from jrotc. Luckily, none I know are serving overseas in combat capacity at the moment. What is most interesting to me, from a hopefully detached perspective, is what the next step for the administration is.
As I see it, there are a few options:
1) do nothing. absolutely nothing. sell it as you have to.
2) do a little. some CIA here, some drones there, maybe some devgru over there. sell it if you have to, or repeat (1)'s defense if its widely unknown
3) guns blazing light. Air-ground assets, no-fly zone, tomahawks, maybe small ground forces, and maybe more of (2).
4) guns blazing heavy. all the toys come out.
I see (1) as impossible because our overlords are way too ADHD to leave something like this alone TRULY.
I see (4)as unlikely because of the massive political capital involved.
2 is more likely than (3) by a factor but both are within the margin of error.
This is my uninformed guess of events to come.
