The Onion, as rather awkwardly reliably, rather nailed it in their op/ed by Assad
. there really isn't any good option, as far as I can see. Even if the recent supposed attack was nerve gas, the options we have available are limited, expensive, and highly destructive against everyone, absent a Bad Guys Only bomb.
My inclination is to withhold for now, given the high risk of not ultimately making things any better, and getting entrenched in yet another military quagmire. If we could simply go after Assad himself, that I'd have few problems with, on the understanding that he would not
be summarily executed to give a US voter approval boost, but rather, a genuine trial, where all parties would be able to offer all the evidence available.
