White House: US ‘absolutely not’ bowing to N. Korean pressure 
  
 By Carlo Muñoz - 
  
 The decision to delay critical U.S missile tests is not a sign that the White House is bowing to North Korea's "bellicose rhetoric," a top administration official said Sunday. 
  
 During an appearance on "Fox News Sunday," senior Obama adviser Dan Pfeiffer said the decision was "absolutely not" a retreat after Pyongyang's recent aggressive actions against the U.S. and its allies in the Western Pacific. 
  
 "The onus is on North Korea to take the step back," Pfeiffer said regarding North Korea's theats of military action on the peninsula. 
  
 The provocative actions taken by North Korean dictator Kim Jong Un fall in line with the regime's long history of saber rattling, he added. 
  
 "North Korea is engaging in the kind of behavior we have seen for many, many years: provocative actions and bellicose rhetoric," Pfeiffer said. 
  
 But those actions, he added, will only "futher isolate" Pyongyang within the international community. 
  
 Pfeffier's commens come shortly after Defense Secretary Chuck Hagel postponed tests of the Minuteman 3 missile at Vandenberg Air Force Base in California. 
  
 The delay was designed to tamp down tensions with Pyongyang, a senior defense official told the Associated Press, which first reported the delay. 
  
 The United States has already deployed a ballistic missile defense system to Guam and moved Navy ships, armed with anti-missile weaponry, off the Korean peninsula. 
  
 In response, Kim has reportedly given his military the green light to launch nuclear strikes against U.S. allies in the Pacific and targets inside the United States. 
  
 White House press secretary Jay Carney on Thursday urged North Korean leader Kim Jong Un to “choose the path to peace” after reports said the nation had deployed missiles to its east coast. ||||| Story highlights Test of the Minuteman III missile was long-planned, a U.S. official says 
  
 Delay of a missile test is "prudent and wise," a U.S. defense official says 
  
 Launch was scheduled for Tuesday at Vandenberg Air Force Base, the official says 
  
 U.S. officials not clear on reports that North Korea has loaded a pair of missiles into launchers 
  
 The United States is delaying a long-planned missile test to avoid any misperceptions by North Korea amid mounting tensions, a senior U.S. Department of Defense official said Saturday. 
  
 Postponing the launch of the Minuteman III intercontinental ballistic missile, initially scheduled for Tuesday at Vandenberg Air Force Base in California, was "prudent and wise," said the official, speaking on condition of anonymity. 
  
 The missile test had nothing to do with North Korea, but the United States decided to hold off "given recent tensions on the Korean Peninsula," the official said. 
  
 "The U.S. will conduct another test soon and remains strongly committed to our nuclear deterrence capabilities," said the official, who was not authorized to publicly release details of the launch.

 Embassies staying put 
  
 Word of the launch delay comes amid bellicose posturing and threats that have grown more dramatic by the day on the Korean Peninsula, including North Korea's warning to foreign diplomats in Pyongyang that if war breaks out, it cannot guarantee their safety. 
  
 On Friday, officials met with ambassadors to ask whether they needed help evacuating their personnel, several diplomatic missions said. 
  
 The same concern apparently does not extend to foreign tourists. 
  
 Amanda Carr, who works for a British travel company, wrapped up a pleasure tour Saturday of North Korea with a group of 20 tourists. Before leaving the country, they were able to take in a rally in Pyongyang. 
  
 The British Embassy in North Korea gave her company, Koryo Tours, some guidance in light of the international tensions. "We've been advised to continue with the tours," Carr said. 
  
 Her North Korean partners -- from the state's travel agency -- continue to accept tourists, she said. And their demeanor is friendly toward them, as it always has been. 
  
 Russia, a traditional ally of North Korea, may consider an evacuation of staff because of the tensions, Russian state media said. 
  
 The Swedish Embassy will remain open as well. It represents the concerns of the United States in North Korea and helps its citizens traveling there. 
  
 British, French and German diplomats also have no immediate plans to leave. 
  
 Meanwhile, U.S. Secretary of State John Kerry will visit Asia next week where he is expected to discuss potential diplomatic incentives for North Korea once it stops its threatening rhetoric, senior administration officials told CNN on condition of anonymity. 
  
 "Secretary Kerry agrees that we have to have a robust deterrent because we really don't' know what these guys will do," said one senior official, who was not authorized to speak on the issue. 
  
 "But he also knows that the North Koreans need a diplomatic off-ramp and that they have to be able to see it."

 Missile tension 
  
 New reports of missile movements in North Korea have triggered military counteractions by South Korea and the United States. 
  
 South Korea's semiofficial Yonhap news agency reported the missiles were ready to launch, citing military sources in Seoul. They are probably Musudan missiles, U.S. officials said. They would have a 2,500-mile range and could threaten South Korea, Japan and Southeast Asia. 
  
 It is believed a North Korean missile launch would be a "test" launch rather than a targeted strike. 
  
 A U.S. official told CNN that two medium-range missiles have been loaded onto mobile launchers on the east coast of North Korea, but a second U.S. official said intelligence on that is not definitive. Both officials spoke on condition of anonymity because they are not authorized to publicly speak on the issue. 
  
 In response, South Korea has sent Aegis destroyers equipped with advanced radar systems to both of its coasts, Yonhap said, citing navy sources. 
  
 The United States will deploy missile defense systems to Guam, a Western Pacific territory that is home to U.S. naval and air bases. North Korea has cited those bases when listing possible targets for missile attacks.

As tensions escalate with North Korea, the US has opted to delay a missile test at Vandenberg Air Force Base in California, CNN reports. The long-planned test of the Minuteman III intercontinental ballistic missile was unrelated to North Korea, but delaying it is "prudent and wise" in light of North Korea's sabre-rattling, said a Pentagon official. Top White House adviser Dan Pfeiffer defended the move today on Fox News Sunday, saying the delay is "absolutely not" a retreat following Pyongyang's aggressive rhetoric, reports The Hill.
