The South Korean government made a rare formal overture to its counterpart in the North on Monday, proposing that the longstanding rivals open new military talks along their shared border. It is the first such offer under South Korea's new president, Moon Jae-in, who signaled his willingness to talk with Pyongyang during his campaign earlier this year.

On the Fourth of July, North Korea marked a milestone by firing an intercontinental ballistic missile that soared high into space before turning around and landing in the sea near Japan. The North's state media said the missile, Hwasong-14, flew 580 miles, reaching an altitude of 1,741 miles, and flew for nearly 40 minutes.

Listen closely to what U.S. officials like to say about America's long security alliance with South Korea, where 28,000 U.S. troops are stationed in bases around the country. Something in the language perpetually pops up:

"America's commitment to defending our allies ... remain[s] ironclad," Defense Secretary Jim Mattis said in Seoul in February.

An American THAAD missile defense system is now operational in South Korea, less than two months after its components arrived there, the U.S. military says.

The system is meant to protect South Korea from ballistic missiles fired by North Korea, the Pentagon says. But China and other critics of the move say it will only increase tensions on the Korean Peninsula. The decision to install the missile shield was made by the U.S. and South Korea last July.

President Trump says that while he would like to resolve the issue of North Korea's nuclear program diplomatically, it will be hard — and there is a potential for a major clash with the Asian nation, Trump said in an interview with Reuters.

"There's a chance that we could end up having a major, major conflict with North Korea, absolutely," the president told the news agency. "We'd love to solve things diplomatically but it's very difficult."

A U.S. Navy strike group has been ordered to relocate to the western Pacific Ocean, providing a physical presence near the Korean Peninsula as concerns mount over North Korea's missile program.

The Pentagon announced the deployment late Saturday. In a statement, U.S. Pacific Command spokesman David Benham said the Carl Vinson Strike Group set sail toward the peninsula from Singapore.

Secretary of State Rex Tillerson says the U.S. doesn't want to take military action against North Korea, but "all of the options are on the table" if a serious threat arises. Tillerson made his frank remarks in a visit to South Korea on Friday, a day after saying diplomatic efforts "have failed" to persuade North Korea to abandon its nuclear program.

Tillerson's Asia tour began in Japan and will end in China. The top American diplomat is traveling without a press contingent.
