North Korea Vows o Strengthen Nukes As US increases Pressure
The U.S. defense chief warned Friday that a military solution to the standoff with North Korea would be "tragic on an unbelievable scale," while the North vowed to rapidly strengthen its nuclear-strike capability as long as it faces a "hostile" U.S. policy.North Korea tested a longer-range missile last weekend, which experts say was a significant advance for a weapons program that aims at having a nuclear-tipped missile that can strike America. The test triggered a new U.S.-backed push for a fresh round of U.N. sanctions against the North.
