Cruz will not be slicing up Trump. Why would Cruz go through the trouble of calling a meeting with Trump, and why would Trump accept, if they were political enemies? Also, Cruz was out there loudly defending Trump regarding his remarks about illegal immigration. That was very risky and not the actions of a man who is out to derail Trump’s candidacy.
Political enemies? No. Political rivals? Most definitely. At the end of the day, Cruz wants the nomination. Right now his biggest competition is Trump and Walker, people taking conservative votes away from him. He has to take both of them out early so he can build strength to finish off Bush. So why is Cruz meeting with Trump and defending Trump? As Winston Churchill said, "When you have to kill a man it costs nothing to be polite."
