Rather than going back to page 8 and responding to kara and luis in detail, I'm going to pick up where the discussion has gone (so my apologies if I miss responding to one of the details you two started talking about).
In my opinion, Sandwich has hit the nail if not precisely then at least closer than some other speculation. Several pages ago I alluded to some specialized units that are funded by various NATO countries. I haven't forgotten about that.
Some of you seem to think that past screwups mean that present action is a poor idea. In hindsight, perhaps arming the rebels wasn't a great idea. Personally, I thought Syria should have received the Libya treatment - a government that fires on civilian protestors quickly learns that it will no longer have modern military equipment to fire on the protestors with because they just got flattened by NATO / Arab league airpower. That was two years ago.
Now, we have the situation today. I'll recap it again for anyone in the audience not paying attention:
1. Chemical weapons attacks have occurred FOUR TIMES in the last 12 months.
2. Both the Syrian government and the rebels have been implicated in said strikes.
3. Assad's forces have targeted civilian populations directly in military strikes, before the rebels were established and after.
4. Arguably, the more desperation faced by any one side, the more likely they are to use chemical weapon stockpiles (historical precedent for this). Ergo, ceasing logistical support to the rebels will increase the odds of greater chemical weapons attacks. Similarly, decimating government forces without eliminating chemical weapon stockpiles will also increase the odds of attacks.
5. The Syrian government hates everyone but Russia, China, and Iran.
6. The Syrian rebels are highly divisive, but the dominant factions likely to win out if the rebels took power hate everyone but Iran and Al-Qaeda.
7. Everyone in authority positions in Syria pretty much despises the West, and will continue to do so.
8. Damascus is a mere stones' throw from the Israeli border, and much as the Syrian rebels and government despise each other AND the West, if there's anyone they hate more it's actually the Israelis. Who happen to also be much hated by Iran.
If we stop arming the rebels, government forces will destroy them and continue the campaign against civilians (religion has only tangentially entered the discussion via linked sources so far, but let me remind everyone that Assad's government is Baath and a minority in Syria; he has no love of the protesting civilians, which are primarily from different Islamic sects and will happily use military force on said civilians to secure his power base. This we do know; this is why I assert that more civilians die without intervention because an Assad victory WILL specifically target civilians).
Now that chemical weapons have been openly used by both sides, we face the problem of escalation. With swift, severe denouncement of the chemical weapons use with actual consequences - which diplomacy has failed to muster for two years - there is no incentive to not use them further. In fact, now that the line was drawn, backing down emboldens both sides. After all, if we promised consequences and failed to deliver them this time, chances are we won't do it next time. This is called appeasement diplomacy and it doesn't work. It never has worked. Britain has tried it numerous times and it has ALWAYS, without fail, backfired and made things worse.
So - strikes into Syria.
It seems that a number of people around here - and public opinion generally - is that strikes are going to be cruise missiles targeting Assad and this is a bad thing. I happen to agree. I also note that this is not what NATO forces appear to be gearing up for, though Assad's forces are being listed as the primary target.
What I suspect will happen - and hope will happen - is a series of missile strikes covering up the deployment of special forces units specifically targeting all known and possible sites of chemical weapons storage in Syria to specifically destroy those stockpiles maintained by both sides. Much like Afghanistan and Iraq (and countless operations before), it would not surprise me in the slightest to learn that elements from SAS / JTF2 / SEAL / Ranger / Delta Force / Mossad / Force Recon or a variety of other units with names the general public won't recognize in the slightest have been parked in Syria for months before now. The probability that they have not been is quite low, considering the precedents set from the early 1980s to the present. Furthermore, I expect we will see specific targeting of Assad's more advanced military hardware capable of delivering chemical weapons strikes (as the majority of the stockpiles appear to remain in the hands of the Syrian government). Expect to see helicopter staging areas and artillery / launchers specifically targeted. This is the form that I think intervention should take and probably will take. Also, the proposition that NATO forces (specifically naval assets) would be lost or heavily damaged in such an intervention is ludicrous.
A few of you keep talking about how the humanitarian justification is bull****. It's hypocrisy, but it isn't bull****. There are very good reasons why the West should be intervening to protect civilians (and luis, much as you say this isn't Rwanda or Sbrenica yet, just watch what would happen if we quit arming the rebels; while murder on religious grounds and affiliation isn't technically genocide, it's close enough).
Regardless, my desire to see a strike in Syria is not motivated primarily by civilian deaths. I think it's an important issue, and it justifies action, but the primary justification in my mind is that chemical weapons attacks need to be denounced and stopped right now before they spread any further, which is an eminently pragmatic position. If these attacks go any further, there is a very real risk of the Syrian civil war expanding across the Middle East. While Iran is already egging on terrorist groups to strike American assets in the Middle East if a strike in Syria occurs, no one will risk actual national military confrontation (least of all the Iranians) over NATO intervention in Syria. If, on the other hand, a chemical weapon strikes hits in or close to Israel, or even targets Israel, all bets on Middle Eastern stability are off. If Israeli forces deploy openly beyond their national borders right now, the Middle East will explode.
