Division 30, the US-supported Syrian rebel group, declared a truce with al Nusra (a branch of al Qa'ida) after facing hard attacks from that group.
It is bizarre to refer to capturing an enemy soldier as "kidnapping".
It is called "taking a prisoner". Al Nusra ought to treat these
captives according to the laws of war, but I don't have much
confidence in its ethical principles.
Division 30 was effectively compelled to do this, because it is too
weak to do otherwise. The US has only managed to train around 50
rebels, and success would require thousands. I take this as further
confirmation that this approach is simply futile.
A few years ago, I said that there was no effective way to intervene
in Syria that would make things any better. All the sides were bad.
The situation has changed since then. PISSI (*) is worse than Assad,
and we can support the revolutionary Kurds of Syria without shame (we
need not suppose they are flawless). They welcome non-Kurds that
accept their secular and egalitarian society.
The US should support the revolutionary Kurds of Syria vigorously.
