I remember the old Star Trek "Ferengi Rules of Acquisition" which included "War is good for business" and "Peace is good for business." It does seem that the former occurs more often than the latter.

Whether we should have been in these sites or not is now moot. Our forces are there. We can't change that regardless of who was right or wrong. So, what's the best way out that will guarantee (as much as possible) no return for a few generations?

As far as why the other countries are not keen to get militarily involved may have to do with the fact that they probably logistically supply all factions ("War is good for business"), but without fanfare.

It's what can be described as a "Devil's Alternative." There is no "win" solution, but which solution results in losing the least - now and especially in the future. It's a shame that clairvoyance isn't a trait amongst all of us.
