You stated that any nation that nuked us would be toast because Obama would hit them back. That is speculation.
No, that would be policy. It's long-standing policy, too.
What you're saying in that Obama wouldn't do that -- now "that" is speculation. There's a difference in saying "This is the policy of the United States" (which can be shown) -- and saying -- "Obama won't follow long-standing nuclear policy." (which is speculation).
On top of that, I can pretty well guarantee you that both Democrats and Republicans would be going "nuclear" over it (if you're forgive the pun) and everyone would be demanding it. There's no President who is going to stand against long-standing policy and against both parties and the American public, all at the same time.
Nope, no one would put up with that one. If you wanted a "sure scenario" to get rid of Obama -- that would be the scenario -- guaranteed... :-)
You are missing the point.
Obama is CIC and is not bound to follow any policy but his own.
The assertion that he WILL follow policy is your opinion.
My opinion is Obama is willing to do just that.
He's a hard head and will not bow to pressure, but he will bow to other world leaders.
