1. The war in Syria has become civil, religious and other minorities are clashing – atrocities are on both sides. There is no “good cause” to defend. Innocents will die on both sides.
2. In fact, if the conflict does not deepen with the intervention of third-party armies, it is very likely to reach a stalemate, in which the resources of the belligerents will not be sufficient to continue active fighting, thus balancing the difficult situation. The bloody revenge of the eventual winner will also be avoided.
3. The whole conflict is more of a proxy confrontation of political cliques (American, Russian, Iranian, etc.). The war (anymore?) is not about liberating one or another people, but about who will be the new local satrap. Just look at these conversations between Putin and the Saudi princes
4. A possible US operation in Syria is more a plan of the US administration than an expression of the opinion of an individual US resident. This Reuters poll shows that 60% of Americans are against the entry of (more) US troops into the troubled country.
5. It has not been confirmed that chemical weapons were used by the regime. Moreover, even an organization with a questionable usefulness like the UN seems rather opposed to intervention based on this thesis. Carla del Ponte's suggestion that the rebels released the poison gas also emerged.
6. If someone really wants to help the Syrians, instead of raining Tomahawk missiles on them, they can lend a hand to the millions of refugees. It will have a much more positive result than bombing their homes.
7. THIS is war, not the stuff you see while playing Star Craft or C&C Red Alert. Do the Syrians need more of it?

Just to add, it's not at all necessary that the gas was released by Assad or the rebels. It's entirely possible that it was a third party, like Al-Qaeda for example (I read somewhere that the rebels supported it).
By the way, if the United States reduces Assad's forces (as I read they want to), then the war will most likely last longer than before. That is, more innocent victims will die.
Add that this will be another war without a UN mandate. And most likely they will not officially declare it in the US (i.e. they will wage an undeclared war). I also read that in order to declare war, Obama had to have the consent of the parliament by the constitution. I highly doubt that he will ask for it and get it (i.e. he will violate the US constitution and get away with it).
