You mean Rand promised to Ron Paul supporters that he will be against Israel? No, Rand actually discussed phasing out US aid with Bibi. But will Pentagon and our taxpayers be ready if Israel sells its technologies to China in order to get cash to buy old F-15? Or may be Israel wont need absolete F-15 anymore?
If aid to Israel bothers you and the issue is about money (and not a hidden agenda to weaken Israel) than consider this: your particular taxes will go to NATO members like Turkey. That money is not considered as foreign aid and wont be cut. Taxes from American Jews will go to Israel. I will support you if you lobby against Turkey.
