I wouldn't criticize it, except for we had no reason to get involved. They aren't our responsibility.
When has that ever stopped the US? Though helping the Libyan rebels was one of the few things I think the US has actually gotten right. Kudos to Obama and his administration for (eventually) doing the right thing.
Yes, because it's entirely Obama's fault that the US is circling the toilet.
Not the millions of other problems that the country has. Or the recent economic issues. Or the fact that it's a dying empire.
And Bush was a terrible President - though it doesn't seem like he was as destructive as any of the current Republican nominees have the potential to be.
