Well, I think US foreign policy is already preordained in the bigger sense; Slowly withdraw from Iraq, reinforce/help the situation in Afghanistan, confront Russia and Iran in non-violent ways (any talk of war with either is just hooplah)strengthen economic ties with China, improve America's tarnished image etc.
So my vote is going to Obama purely for domestic reasons, I don't like republican policies which give big business a free pass and enrich the already super-wealthy. Also I'm a social liberal, which pretty much means I won't ever vote Republican
