Sometimes people use wrong words. I read the context of the sentence, which included the word 'Obamanomics', which registers to me as being related to economics, which does not register to me as being related to fighting in a war. Therefore, I based my 'read' of the word on the notion that he did not actually mean "flee" as in "run for your lives, henny penny, the sky is falling", but rather to simply 'leave'.
Had his post said, "If due to impending war, you were forced to flee the US, where would you go?" I would have read it as "run for your life".
I am not, nor will I ever be, a literalist. I tend to read context and interpret word usage thus. Sometimes I am right, and sometimes I am wrong. C'est la vie.
