Obama’s response...
“Fore!”
I hate to mention this, but we are broke. Not only that, but our military is being destroyed by endless deployments in futile operations in the Middle East. So, how on earth could the US do anything about what Russia or China or any other country is doing? We are finished as a power, and even if we were not, what would you propose we do when some country pimps with Norway? Are we responsible for defending every country on earth? Most of these countries would not pee on us if we were on fire. Let them defend themselves for a change.
