To put it bluntly ,We simply cant afford another war.

We are not a world power with vast resources like America and we can no longer act like we are still an empire ,Those days have long gone !.

The reason we ain't going into syria is cause where not stupid, China and russia is Game over. thing with america is they think they run everything but they dont and everything will be judged pretty soon as for france wow lol they should blow there own fleet up now, save others the time

The truth is often unpopular Smeargle but it is still the truth.

It's the members of parliament who are preventing it. Now that new evidence has been released, people are debating whether or not to try and attempt it again.

"Bombs kills people, bullets kill people why should chemical weapons be on a different level". Chemical weapons are on a different level because they are not controllable. And instead of killing people straight with bullets, Chemical weapons can re-shape the human body and cause long term pain and suffering so therefore it was agreed by the UN that there will be NO chemical warfare. Look up what chemical weapons can do to you...

You said it yourself, the rebels themselves probably used Sarin.
I hope the US do intervene, then we can laugh as they support Al-Nusra, a terrorist group by their own standards.

Oh, and bombs can blow off your arms and leave you in pain for life if they don't kill you - chemical weapons aren't much different.
