Where has Ron Paul said that the US should throw Israel under the bus?
The only thing he's stated is that it's not in our interest to subsidize and control them. Do you disagree with that? Do you believe that the role of US foreign policy is not to protect American interests but to protect what we think is in the interest of other countries?
By saying he doesn't care if Iran gets nukes, dismissing Iran's threats to attack Israel, ignoring the support Iran gave to insurgents in Iraq, ignoring/downplaying the enormous threat Israel faces in the region, dismissing the established relationship we have with Israel, not carefully considering the need to have an ally in a region full of people who want to kill Americans, etc., etc.
I disagree with much of what Ron Paul says about foreign policy. I don't like the amount of foreign aid we give to other countries, but that's about the only thing I can think of that I agree with him on when it comes to foreign policy. And that's because he only talks about three things primarily: closing all military bases around the world, not spending "trillions of dollars on these wars," and ending all foreign aid.
