Striking North Korea first could be 'catastrophic'

WASHINGTON (AP) — A pre-emptive military strike may be among the "pretty severe things" President Donald Trump says he is considering for North Korea, but it's a step so fraught with risk it ranks as among the unlikeliest options.

Even a so-called surgical strike aimed at the North's partially hidden nuclear and missile force is unlikely to destroy the arsenal or stop its leader, Kim Jong Un, from swiftly retaliating with long-range artillery that could kill stunning numbers in South Korea within minutes.

An all-out conflict could then ensue. And while Trump's Pentagon chief, Jim Mattis, says the U.S. would prevail, he believes it would be "a catastrophic war."

In Poland on Thursday, Trump said the time has arrived to confront North Korea.

"I don't like to talk about what I have planned, but I have some pretty severe things that we're thinking about," the president said. "That doesn't mean we're going to do them."

Trump didn't mention which "severe" options he is weighing following North Korea's July 4 test-launch of an intercontinental ballistic missile. The administration has been reviewing its overall North Korea policy for months, having declared earlier attempts at "strategic patience" with the North to have failed. The administration has spoken about starving North Korea of cash for its nuclear program and getting other countries to add diplomatic and economic pressure.

But Trump and his aides have not have ruled out the possibility of war with an adversary that is openly defying U.N. Security Council resolutions and threatening the United States.

"It's a shame that they're behaving this way," Trump said, "but they are behaving in a very, very dangerous manner and something will have to be done about it."

Trump was referring to North Korea's test-launch Tuesday of an unarmed ballistic missile that for the first time demonstrated the range needed to reach U.S. soil. The ICBM was launched on a lofted trajectory so that it fell short of Japan. U.S. analysts calculated if it is launched on a standard attack trajectory, the missile could reach Alaska. With further testing, they say, North Korea will achieve even longer ranges.

The missile launch created a new reality for the U.S. and its South Korean and Japanese allies, which already are in range of the North's missiles. With a population of more than 20 million, Seoul is in easy range of North Korea's massive array of artillery guns north of the Demilitarized Zone that forms a buffer between North and South. Japan could also be a target. Beyond the nuclear threat, the North also is believed to have chemical and biological weapons.

The U.S. has about 28,000 troops in South Korea, and Gen. Joseph Dunford, chairman of the Joint Chiefs of Staff, says about 300,000 U.S. citizens are in Seoul alone.
