Can North Korea REALLY attack Austin? Experts scoff at Kim Jong Un's ham-fisted threats on map that just happened to show attack plan with 'non-existent' missiles North Korea said it had entered a 'state of war' with South Korea Rogue state also threatened to shut down a border factory complex that's the last major symbol of inter-Korean cooperation By Daniel Miller and Daily Mail Reporter North Korea may have key U.S. cities - and Austin - in its nuclear crosshairs, but most analysts agree that the reclusive totalitarian regime is all bark and no bite. The sabre-rattling North Korean government unveiled its 'U.S. mainland strike plan' Friday featuring a map showing Hawaii, Washington DC, Los Angeles and the capital of Texas as the targets. NK News published photos showing Kim Jong Un at an 'emergency meeting' with his military advisers in a room plastered with large-scale maps showing what appear to be missile trajectories pointing to American cities. Trajectory: By superimposing a map of the U.S. onto the photograph of the North Korean war room, researchers at the University of Alabama were able to chart its predicted path Nascent technology: A map from the Federation of American Scientists and the Center for Non-proliferation Studies shows that North Korea's missiles cannot even reach India about 3,100 miles away Worst-case scenario: North Korea's best hope to score a strike on a U.S. territory would be to fire the Taepodong-2 rocket, which could possibly make it to Alaska Western weapons experts wasted no time ridiculing Kim Jong Un's ambitious plan to attack the US. 'How clumsy of #NKorea to accidentally display their US Mainland Striking Plan -- with ICBMs [Intercontinental Ballistic Missiles] that don't exist,' tweeted Mark Fitzpatrick, director of the non-proliferation and disarmament program for the International Institute for Strategic Studies, according to Foreign Affairs. Other analysts also chimed in, among them James Hardy, the editor of IHS Jane's Defense Weekly, who wrote that there is little chance North Korea could land a missile anywhere outside the Korean Peninsula. While there is a small chance that the U.S. intelligence community is grossly underestimating North Korea's weapons capabilities, the consensus among most experts is that the missiles believed to be in the Asian nation's arsenal could not come anywhere near continental U.S. A map from the Federation of American Scientists and the Center for Non-proliferation Studies shows that North Korea's operational missile capacity cannot even reach India about 3,100 miles away, to say nothing of Austin located more than 6,000 miles away. Iron shield: Graphic showing how the U.S. missile defense system would defend the U.S. against a North Korean missile attack Arsenal: The Taepodong-2 rocket is designed to have a range of more than 6,000 miles It is believed that Un's regime currently has six types of rockets in its nuclear cache at different stages of development. Hwasong-5 and Hwasong-6 have the shortest ranges at 180 and 310 miles, respectively. The only operational long-range missile is believed to be the Musuadan, which could reach territories just over 1,800 miles away. North Korea's best hope to score a strike on a U.S. territory would be to fire the Taepodong-2 rocket, which could possibly make it to Alaska, but no further, according to the Council on Foreign Relations. As North Korea continues to ratchet up the rhetoric, the country warned Seoul on Saturday that the Korean Peninsula had entered 'a state of war.' The North also threatened to shut down the Kaesong industrial zone, a border factory complex that is the last major symbol of inter-Korean cooperation, if Seoul continued to 'insult its integrity.' This is the latest in a series sabre-rattling announcements from the rogue state since the United Nations imposed new sanctions in response to the country's latest nuclear test last month. The White House said it takes these announcements seriously but added that Pyongyang has a long history of bellicose rhetoric. Declaration: North Korea's young leader Kim Jong Un pictured on Thursday this week. The rogue state announced today that it is at war with the South In today's announcement, North Korea said that all matters between it and the south will now be dealt with in a manner befitting war. 'From this time on, the North-South relations will be entering the state of war and all issues raised between the North and the South will be handled accordingly,' a statement carried by the North's official KCNA news agency said. A White House spokesman said: 'We've seen reports of a new and unconstructive statement from North Korea. We take these threats seriously and remain in close contact with our South Korean allies,' said Caitlin Hayden, spokeswoman for the White House National Security Council. 'But, we would also note that North Korea has a long history of bellicose rhetoric and threats and today's announcement follows that familiar pattern,' she said.

The Pentagon has also been beefing up U.S. missile defense capabilities on the West Coast. The United States has been stressing that it has the capability and willingness to protect itself and U.S. allies in the region. 'We remain fully prepared and capable of defending and protecting the United States and our allies,' said Hayden. Kaesong Industrial Park is located six miles north of the Demilitarized Zone and was opened in December 2004. The zone is mutually beneficial as it provides the north with a source of foreign currency and the south with a supply of cheap labour. An estimated 53,507 North Korean workers were believed to be employed in Kaesong at the end of 2012. In 2012 wages in Kaesong were estimated to be around a fifth of the South Korean minimum wage, and about a quarter of typical Chinese wages. It means firms are able compete with China in the production of low-end goods such as shoes, clothes, and watches. Kaesong is linked by road and rail and an estimated but there are strict border checks from both sides and defections are rare. 'We continue to take additional measures against the North Korean threat, including our plan to increase the U.S. ground-based interceptors and early warning and tracking radar,' and the recent signing of a South Korean-U.S. counter-provocation plan. Britain's Foreign Office said such threatening statements would 'only seek to isolate it further.' A spokesman said: 'We have noted today's statement from North Korea. We have made clear to North Korea that its long-term interests will only be served by constructive engagement with the international community. These threatening statements will only seek to isolate it further. 'The armistice agreement has enabled the Korean peninsula to benefit from 60 years' peace. Maintaining it is in the best interests of all. The Kaesong industrial zone is a source of hard currency for the impoverished state and hundreds of South Korean workers and vehicles enter daily after crossing the heavily armed border between the rivals. 'If the puppet traitor group continues to mention the fact Kaesong industrial zone is being kept operating and damages our dignity, it will be mercilessly shut off and shut down,' the North's KCNA news agency quoted an agency that operates the factory park just miles north of the rivals' armed border as saying. The two Koreas have been technically in a state of war for six decades under an armistice that ended their 1950-53 conflict. Pyongyang said it was scrapping the war armistice earlier this month. Despite its threats few people see any indication Pyongyang will risk a near-certain defeat by re-starting full-scale war. The South brushed off the statement as little more than tough talk saying was no sign of unusual activity in the North's military or anything to suggest an imminent aggression. North Korea has been threatening to attack the South and U.S. military bases almost on a daily basis since the beginning of March, when U.S. and South Korean militaries started routine drills. Yesterday, pictures were released of Kim Jong Un inside his military command centre signing the order to put rockets on standby to attack the U.S. The pictures, which appeared in the state-run Rodong newspaper, show Kim surrounded by his generals, large-scale maps and diagrams during an 'emergency meeting' at an undisclosed location. A chart marked 'U.S. mainland strike plan' appears to show missile trajectories that the NK News web Declaration: North Korea's young leader Kim Jong Un pictured on Thursday this week. The rogue state announced today that it is at war with the South. However closer inspection of the chart shows the flight path missing these targets as it cuts through California, Arizona, New Mexico, Texas, Oklahoma, Arkansas, Mississippi, Alabama, Georgia and South Carolina. The order from Kim Jong Un came after the U.S. flew two stealth bombers over the Korean peninsula as part of a joint military exercise. The 30-year-old leader warned his forces were ready 'to settle accounts with the U.S.' after the nuclear-capable bombers dropped dummy munitions on a South Korean island range as part of joint drills and returned to their base in Missouri. Many Western experts believe the aggressive posturing is part of a grand master plan to force Washington to the negotiating table and put pressure the new president in Seoul to change policy on North Korea. The images - which show a pair of U.S. Air Force B-2 bombers soaring over an American military base south of Seoul - were taken after it emerged North Korea had digitally doctored a state photo of military hovercraft to make the fleet appear bigger than it was. The photo, issued by the Korean Central News Agency and widely carried in the international media on Tuesday, was said to show the hovercraft coming ashore on North Korea's east coast the previous day. But on closer examination the photograph seems to have been doctored, with images of two hovercraft each used twice and another pasted in. The stealth bomber drill was carried out after North Korea declared it was severing its key hotline to Seoul, amid anger over joint U.S. and South Korean military drills and tough sanctions imposed in the wake of Pyongyang's recent nuclear test.
