The "This doesn't affect us" argument is weak

53. Regime change just opens up a huge can of worms.

It's completely off the table at the UN - the Security Council won't endorse force to deal with the chemical weapon attacks. They certainly won't approve of anything that could result in regime change, such as overthrowing Assad. Russia and China won't have it at all.

We'd have to do it unilaterally, and there's so little support that even Britain's Parliament backed out. We're for the most part on our own

And once we do this, then we have to figure out how to ensure that the guy replacing Assad isn't as bad or worse. There's no good solution to that problem, and everyone's fed up with the "He's a bastard, but he's our bastard" technique of propping up puppet dictators.

The truth is that there are no good options. We can provide humanitarian aid, help build refugee camps, fund Doctors Without Borders and the Red Cross/Red Crescent. We can also impose economic sanctions, and push to freeze international assets for Assad's regime to push them to stop the chem attacks, and I think that's the best we can do.
