Many of the same people who liked his policies and politics in 2008 will not be put off by this at all. They would love to see the US "get whats coming to them", even if it is at the hands of the Russians.
I've never bought into the whole "enemy of my enemy is my friend" cliche, but some of the unthinking, short sighted, G-D America crowd will lap that up like babies milk.
Obama has been on both sides of this issue, said a deterrent to the Russians wasn’t neccessary in 2008, then he said that well, we should deter Russians in 2010, then the leaked video reveals that he totally intended the opposite. It’s interesting how many sides Obama has taken the whole time around as president.
