I shall address only one of your points, regarding diplomacy. I believe very strongly in diplomacy, including ones that are back channel. Nevertheless, such diplomacy must be sanctioned by the government, and it cannot be conducted by defying the government. Indeed, visits of enemy states by parliamentarians undermines diplomatic efforts that might be taking place in secret. Furthermore, these MKs base their argument on their right as Arabs to visit any Arab country. That is not an acceptable position.
