US national security adviser John Bolton does not consider Donald Trump and Kim Jong Un’s summit a failure.

According to him, it is not a failure at all as American national interests are protected.

"Well I don't consider the summit a failure. I consider it a success defined as the president protecting and advancing American national interest. There was extensive preparation for this meeting. Extensive discussions between the president and Kim Jong Un and- and the issue really was whether North Korea was prepared to accept what the president called "the big deal," which is denuclearize entirely under a definition the president handed to Kim Jong Un and have the potential for an enormous economic future or try and do something less than that which was unacceptable to us. So the president held firm to his view. He deepened his relationship with Kim Jong Un. I don't view it as a failure at all when American national interests are protected,” he said in an interview to CBS. 

As reported earlier, the US President Donald Trump and North Korean leader Kim Jong Un’s summit on nuclear disarmament ended with no deal and even without a joint statement.
