Will Obama's Legacy Include Spread of Sharia Law?

What will Obama be remembered for 50 or 100 years from now? Increased spending and a poor economy are no-brainers. But I think there is a good chance that Obama's support for the overthrow of Tunisia, Egypt, and Libya will be remembered, and currently all three are moving toward more radical sharia law. See here, here, and here.

Was this Obama's plan? Or is this another Obama-failure?
