What do you mean?
I explained this previously. In the debates Romney said he thought the biggest future foreign policy problem would be Russia. Obama snarkily replied (with something I bet he had ready to use as needed) “The 1980s are calling and they want their foreign policy back.
It was intended to make Romney look stupid but now we see that Russia again has become a problem - potentially a very big one. As usual the arrogant Obama is wrong but he got what he wanted so what does he care.
