See, in other words you're basically saying we should arm people who use chemical weapons.
Basically this was a conflict we shouldn't have gotten into in the first place, went about getting into it in a completely ****ed up way when we did, ended up supporting a side who completely hates us and now you're suggesting we bomb both sides as if that won't some how result in an even bigger cluster**** than we've already got.
Every move the west has done in this Syrian conflict has been wrong so far. There comes a time when you've got to learn to stop sticking your dick in the wasps nest.
The whole reason the West got involved in the Syria conflict to begin with is because Assad started turning government troops on civilian protestors. So unless you favour the
Rwandan approach to wholesale slaughter of civilians by government-backed forces, I'm not sure how you think this thing could have gone better without putting a UN-backed force in-country which Russia and China were not about to let happen.
To recap:
-Assad's regime turned military-grade weapons on civilian protestors and rebels alike.
-The rebels, who militarily protected civilian protestors from Assad, were losing badly because Russia continued to arm Assad.
-The UN Security Council was rendered useless.
-The West (NATO), despite being mindful of the consequences, proceeded to arm the rebels.
-Conflict continued; refugees fled away from Damascus and near or into neighboring countries.
-Four chemical weapons attacks over an 8 month period; intel shows use by both rebels and government forces.
-Most recent chemical attack hits Damascus, a mere stone's throw from the border of a neighboring country that just happens to be the one Syria and Iran's governments most hate in the entire region, a sentiment in which they are also joined by the extremist factions among the rebel forces.
-Despite numerous diplomatic overtures and threats, no change in policy or mission of Assad's forces.
So, options:
1. Do nothing. Allow wholesale civilian slaughter like Rwanda. Make it abundantly clear the UN Security Council has failed its mandate, and allow Assad to commit mass murder with impunity.
2. Invade. This option dismissed out of hand.
3. Back rebels so long as Russia backs Assad, despite knowing these are not people we want forming a replacement government.
4. Keep trying at already-failed diplomacy. See also option 1.
5* If chemical weapons attacks occur:
a. Do nothing. Hope for the best. No consequences for either side.
b. Military strikes to deter future attacks.
Appeasement-style diplomacy with an aggressive, determined opponent has never worked. The "Do nothing" options look very appealing, right up until you expand the consequences. Granted, doing nothing could lead to nothing more than wholesale slaughter of civilians. The citizens of most Western democracies have ignored such trivialities in the past, naturally. The trouble is that the probability of conflict expansion in the short term as the rebel forces get increasingly desperate and it is demonstrated that there are no consequences to chemical weapons use is much higher than with intervention.
I feel like we're going in circles. It is possible - and utterly pragmatic - to acknowledge the screwups in Western policy historically and still recognize that short-term strikes against the conflicting forces in Syria are the best of the available options we have if we care about civilian death toll and chemical weapons detterrence. If you can ignore both of those issues as minor matters, then I suppose the best course of action is to do nothing, but I have a great, big, gigantic problem with any democracy that purports to protect human rights and can allow civilian murder and CBRNE weapons use on civilians to go unchecked, which is precisely what doing nothing or further 'diplomacy' does so long as the Russians and Chinese aren't engaged. And they show no signs of engaging.
