"will it be the U.S. or will it be China, because from a U.S. point of view it cannot be both"
Yes, it can. See my post above.
Your post is irrelevant because it assumes that the US will allow this double dealing to go on. The U.S should force Israel to choose and then let it live with the consequences. Also, your comment about arming islamofascists is pretty amusing considering Israel is doing everything in their power to arm over a billion communists...
You're saying it can be both? That Israel should not face strong U.S. reactions for its military hardware trade with China? Or that that trade does not matter?
What does your "Yes It can" mean?
