You've got a warped view of friendship. A "true friend" doesn't call you a terrorist. They don't spit in your face and stab you in the back. That's what the anti-port faction is doing.
True friends of America support Israel; they don't prohibit goods going to or from Israel from entering or being shipped through the ports they control. Somehow I do not think that America's Jewish population wants people that hate their guts controling American ports.
