Didn't we fall for WMD in the desert once before?
The US has no business in a civil war.
		
		
	 
First of all, who's 'we'? The Bush people didn't 'fall for' WMD, they intentionally pushed the story knowing they didn't have the evidence for it. Some people 'fell for' their story.
Second, this is different. We so often make the mistake in policy of reacting t the last situation.
If we're too fast war last time, we have to not go to war the next. If we're too slow to war the last time, we won't make that mistake this time, go to war!
There is no question, it seems, that Sarin was used to kill a lot of Syrian civilians, and strong evidence that Assad's regime did it, as the President laid out last night.
Sorry, but his credibility on these things is a lot higher than Bush's IMO. This isn't about the facts of the Sarin attacks, it's not about 'falling for' a lie about them.
It's about deciding what the right response is to their use.
You're mixing up the civil war with the WMD use.
It's also not about the US getting into the civil war, mostly - but on this one there is a bit of an issue.
This is primarily about responding to the use of Sarin, not the civil war. Assad has killed over 100,000 people, while the US has done little. That's both a tragic situation and one in which Obama has not gotten very involved other than some minor support like some guns - right or wrong.
However, the resolution the Senate committee passed added an amendment by John McCain making it the US policy to take actions which WILL be enough to turn the tide of the civil war in favor of the rebels - so the Congress to this point has raised our getting more involved, though not with troops. But the full Congress has been unlikely to pass it.
And you're also ignoring that this isn't simply a civil war. Assad has the backing of Russia and Iran against the rebels.
This comes up over and over, about dictators versus their own people. Historically sometimes we're the country backing the dictator; sometimes others are as in this case.
These situations are always tragic wars - just saying 'we have no business' no matter how ruthless the killing of the people (or how bad the rebels) is problematic. If we hadn't been at war with Germany in WWII, would the holocaust have been 'any of our business' to consider taking action to protect the victims in?
There's a case for the US 'taking sides' in civil wars, hopefully in favor of a side for the right reasons and not for the wrong ones (hey, they dictator sells his resources to us, cheap).
Consider the uprising in Libya - we took sides. Analysts say without outside help the rebels would have been slaughted. But the west got involved, and the rebels won.
Was it wrong to not just stand by while the people under that dictator were slaughtered? And the rest left powerless under tyranny?
But even though there is a case to get involved in some civil wars - this issue isn't about getting involved in Syria's. It would have an effect on it - but it's about the Sarin use.
You didn't answer Obama's question - if the use of Sari gets no response, what's to stop its being used against and again, by more and more dictators, with impunity?
