The only missile that could reach any U.S. territory, the Taepodong-2, has been tested only once, and it failed. Such a missile would have a range of 4,200 miles, enough to reach Alaska and Hawaii.
For all of these reasons, many experts don't take a North Korean missile attack on U.S. territories seriously.
Coyle said he thinks North Korea's recent displays of belligerence are a means of bullying other countries to give it oil. He noted that in the agreements signed with Pyongyang in the 1990s, the U.S. agreed to deliver 500,000 tons of oil yearly at no cost and help them build a nuclear reactor for energy.
"North Korea is looking for leverage wherever they can get it," Coyle said. "But they don't have much more than bluff and bluster at their disposal. The DPRK desperately needs oil and gas energy resources, but has none. Zero. That's why in every negotiation they ask for promises of oil."
