Many are worried about recent comments out of North Korea. The rogue nation has made threats that it could hit Australia with "disaster" because Australia has taken sides with the United States rather than with North Korea and its reclusive regime. Granted, when it comes to Australia, these may be little more than idle threats. Australia's Foreign Minister, Julie Bishop, has insisted that Australia is "not a primary target." However, virtually everyone agrees that the United States is not alone in facing danger from North Korea. This increasingly volatile isolationist country has taken significant steps forward in its nuclear and missile capabilities. How much of the world is at risk of attack from North Korea? Experts warn that the country possesses a vast arsenal of short-range ballistic missiles. North Korea has successfully tested them some 50 times, with only one of those tests failing. Thus, their current leader, Kim Jong-un, no doubt feels confident in their ability to hit nearby targets. These missiles are capable of reaching all of South Korea, as well as Japan's second largest city, Osaka. Some of these missiles are likely capable of evading the THAD defense system that the United States has stationed in South Korea. What about North Korea's medium-range ballistic missiles? These also have been reliable tested, with just 2 tests failing out of the 9 that have been conducted. The medium-range ballistic missiles have a range that includes all of Japan, including Tokyo, which is the world's largest metropolis. Another threat comes from intermediate-range ballistic missiles. These missiles are clearly capable of reaching U.S. military bases on Guam. They also put much of South-East Asia on alert. Most worrisome for many are intercontinental ballistic missiles. North Korea has successfully tested these twice. Such missiles are at least capable of reaching the U.S. state of Alaska, as well as many parts of Australia. According to some estimates, it is possible that all of Australia is actually within range, as well as Los Angeles and most of Europe. Clearly, all eyes are on North Korea and the ongoing efforts to denuclearize the rogue nation.
