No- Buchanan is just like Bush I who refused to allow Israel to defend themselves during the first gulf war. He doesn’t hate Jews or even Israel, he just finds their existence to be problematic to his ideas of Mid East policy-pacify the Arabs and keep the oil flowing.
We had our troops in neighboring Arab states and didn't need the whole region coming unhinged in a wider war. It was our responsibility to stop the scuds targeting Israel during gulf war 1 and for the most part we did.
