There has been talks of negotiating a nuclear treaty with Iran. However, this is not safe. The burning of our American flag alongside the Israeli flag followed by chants of "death to Israel" and "death to America" display that they do not wish peace with us but destruction and if we sign this treaty, we are, in essence, signing out death certificate because they will use it against it.
Alongside this, it has always been our policy as the United States of America to NEVER negotiate with terrorists. That means never. No matter what. This is to preserve us as a nation lest we instead wish to concede defeat to any who wish to demand of us and realize they will get their way.
Do not cave to terrorists.
