Answer: Kang wanted the USA to suffer famine and be a 3rd world country. His plan was to get in, set off all the warheads and plunge the USA into the dark ages. During one of the exchanges between Kang and Mike, Kang says "I just want the USA to experience poverty and famine." So he had no plans to survive his mission. He needed the president to gain the 3rd code incase it couldn't be broken by the hacker. He faked the presidents death to give himself more time with the president.
