CRUZ: And I'll tell you, frankly one concern I have with Donald is that although his language is quite incendiary, when you look at his substantive policies on Iran, he has said he would not rip up this Iranian nuclear deal. I think that's a mistake.
TRUMP: If I become president of the United States, one of the things that will be an absolute priority is number one, protection of Israel, but also seeing if a deal can be made, the toughest deal, the toughest negotiation there probably is of any kind no matter where you look, no matter how hard you look.
CLARE M. LOPEZ: "The Center for Security Policy explained the Treaty of Hudaybiyyah in its 2010 book, "Shariah: The Threat to America." The context is about situations in which Muslim forces might lawfully enter into a treaty or truce with the enemy. With troubling ramifications for current day negotiations, those situations demonstrate the centrality and importance of deceit in any agreement between Muslims and infidels. As it is recounted, in the year 628 CE, Muhammad (whose forces already controlled Medina) agreed to a 10-year truce with the pagan Quraysh tribe of Mecca, primarily because he realized that his forces were not strong enough to take the city at the time. Islamic doctrine in fact forbids Muslims from entering into a jihad or battle without the reasonable certainty of being able to prevail. In such cases, as with Muhammad, Muslims are permitted to enter into a temporary ceasefire or hudna, with the proviso that no such truce may exceed 10 years (because that's the length of the agreement Muhammad signed). And so, Muhammad agreed to the Treaty of Hudaybiyyah. But just two years later, in 630 CE, now with some 10,000 fighters under his command, Muhammad broke the treaty and marched into Mecca."
