North Korea is now claiming that it can wipe Manhattan off the map with a hydrogen bomb. 
  
 "Our hydrogen bomb is much bigger than the one developed by the Soviet Union," North Korea’s state-run news outlet DPRK Today reported Sunday, according to the Washington Post.

 "If this H-bomb were to be mounted on an inter-continental ballistic missile and fall on Manhattan in New York City, all the people there would be killed immediately and the city would burn down to ashes," the outlet boasted.

 The new bomb “surpasses our imagination,” nuclear scientist Cho Hyong Il told the North Korean news source. 
  
 This is just the latest in a string of claims about the country's capabilities. 
  
 In January, Kim Jong Un said that his country successfully detonated a hydrogen bomb during the nation’s fourth nuclear test. 
  
 Experts cast doubt on the brazen claim, noting that the seismic waves were similar to the last three tests, which were all simple atomic bombs.

 In February, the isolated nation claimed that it used a rocket to put an observation satellite into orbit. Although North Korea has a history of exaggerating military capabilities, South Korea and the Pentagon both confirmed the claim, according to the Washington paper. 
  
 The satellite launch raised concerns about the nation’s progress toward a functional long-range ballistic missile program.

 Experts agree that North Korea probably has the capability of launching missiles that could reach the West Coast, but till now there has been no indication that the nation would be able to hit the East Coast. 
  
 On Friday, North Korea’s state media said that Kim has ordered more nuclear tests. ||||| U.S. Army's armored vehicles take on a position during an annual exercise in Yeoncheon, near the border with North Korea, Monday, March 7, 2016.

 SEOUL, South Korea (AP) — When North Korea makes threats to nuke its enemies, as it has twice over the last several days, outsiders often have one of two reactions: to dismiss it as yet another example of empty propaganda or to panic. 
  
 There are good reasons to do neither. There are many ways the North can retaliate that fall short of war, nuclear or conventional. 
  
 North Korea's latest warning came Monday in response to the beginning of annual South Korean-U.S. military drills, and included vows to turn its enemies into "seas in flames and ashes" with nuclear missiles aimed at South Korea, U.S. bases in the Pacific and the U.S. mainland. 
  
 Pyongyang always responds furiously to the springtime South Korean-U.S. drills, which it views as an invasion rehearsal. This year's drills are the largest ever, meant to respond to the North's recent nuclear test and long-range rocket launch. South Korea's Yonhap news agency, citing unidentified military sources, reported that the allies will work on drills for precision attacks on North Korean leadership and its nuclear and missile arsenal in the event of war. 
  
 The first thing to keep in mind is that Pyongyang's near-term nuclear warnings are mostly bluff; more of a strong deterrent that Pyongyang can use in its propaganda, rather than an actual sign of imminent war. 
  
 The North knows that its atomic program, which is still relatively primitive, is outgunned by the thousands of warheads the United States possesses. Pyongyang is very unlikely to do something that could lead to overwhelming retaliation by superior militaries in the United States and South Korea, and therefore end the ruling autocratic Kim dynasty in Pyongyang. 
  
 Still, the bellicose bluster is not without danger. 
  
 North Korea is so poorly understood by outsiders, even by analysts in the South, that its threats make the already jittery Korean Peninsula even tenser. This general anxiety causes both Korean militaries to bolster their positions and increases the possibility that a misjudgment by North Korea's young leader, Kim Jong Un, could lead to an escalation of violence should a skirmish erupt. South Korea has vowed to hit back hard on future North Korean attacks, raising the possibility of escalation. 
  
 South Korean analysts believe North Korea will follow its nuclear threats with some sort of low-level provocation. It launched short-range projectiles last week, hours after the U.N. Security Council approved new sanctions, and it could fire more missiles or artillery pieces into the sea as a show of force. It also could stage a cyberattack, which South Korea says Pyongyang has done in the past. 
  
 Rather than traditional military confrontations, in which it would be heavily outgunned, the North favors covert, surprise attacks that South Korea cannot immediately respond to. In 2010, North Korea was said to have staged a torpedo attack on a South Korean warship and an artillery bombardment on a South Korean island that killed a total of 50 South Koreans. The ship sinking happened when South Korean and U.S. militaries were conducting springtime military drills. 
  
 North Korea denies it torpedoed the South Korean ship, though it acknowledges shelling the South's frontline Yeonpyeong Island, its first attack on a civilian area in South Korea since the end of the 1950-53 Korean War. 
  
 The North's tenaciousness marks another reason the threats should worry. 
  
 The exact status of North Korea's nuclear weapons program is a mystery, but a general outside consensus is that North Korea has yet to master the technology needed to build a nuclear-armed missile that can directly attack the U.S. mainland. 
  
 Still, after four rounds of tests since 2006, the North is thought to have a handful of rudimentary nuclear bombs. Some analysts think it can arm shorter-range missiles with warheads. And even a crude nuclear weapon could be delivered by other means, such as a plane. 
  
 The country, one of the world's poorest, has also successfully sent satellites into orbit twice, rocket launches that outsiders say were covers for tests of banned technology used in long-range missile firing. Seoul defense officials believe North Korea doesn't yet have a workable re-entry vehicle necessary to get a warhead safely back into the Earth's atmosphere; this is something not tested in satellite launches. 
  
 Analysts, however, believe it's only a matter of time before North Korea gets a reliable intercontinental ballistic missile because its scientists will continue to explode new, advanced atomic devices, and send up rockets, to improve their designs and technologies.

In North Korea's latest hint that it's displeased with the West, it has threatened to wipe out Manhattan with a hydrogen bomb so powerful it surpasses the imagination. "Our hydrogen bomb is much bigger than the one developed by the Soviet Union," a North Korean government nuclear scientist told state media, per the Washington Post. "If this H-bomb were to be mounted on an intercontinental ballistic missile and fall on Manhattan in New York City, all the people there would be killed immediately and the city would burn down to ashes." Experts say this is the first time that Pyongyang has suggested it's capable of striking the US East Coast, the New York Daily News reports. Experts aren't sure of the exact size and scale of North Korea's nuclear weapons program, though obliterating Manhattan with an H-bomb is thought to be well beyond its capabilities. This month alone, North Korea has also boasted of having missile-ready miniaturized nuclear warheads and threatened a "nuclear strike of justice." When Pyongyang makes nuclear threats, other countries tend to either panic or completely dismiss them as bluster, the AP notes. The more appropriate response may be somewhere in the middle: The threats tend to be followed not by massive strikes, but by low-level attacks on the South and missile tests that move its weapons program a little further along.
