There are common rules that all diplomats who have been assigned as ambassadors to foreign nations are expected to respect. They must always remember the post of ambassador demands that the individual stay out of the internal politics of the host nation. The Israel Ambassador to the United States of America, Mr.Ron Dermer, has for years been a friend of Republicans and does not like the Democratic Party of America. There is no problem with an ambassador having opinions, but he is a guest and thus if he breaks rules of the diplomatic trade can be sent packing and returned to his native land. Ron Dermer broke every single rule of the role of ambassador. An ambassador is allowed to talk with members of the opposition party in a nation. But, the ambassador is NOT allowed to negotiate with these people about foreign policy.
If Prime Minister Benjamin Netanyahu is really sorry for his remarks he will immediately recall his ambassador to the United States and dispatch someone who minds his own business and stays out of American politics. This would signal a sign that Bibi intends to behave and seek to work with American leaders. Sorry Bibi, but neither you nor your ambassador are American citizens and you are guests in our land!
