I think we will have to deal with the war on terror on our own shores first and I have no desire to see American troops die for those degenerate, ungrateful bastards in Europe.
When the media start running scenes of starving urchin with the obligatory flies about their swollen heads and victims of mass rape and ethnic cleansing you will hear the congress critters pontificate and BAM we will get drawn in.
Notice I did not state on what side we would be on in this future European war...
