The United States and South Korea begin joint naval maneuvers

The United States is South Korea's main security ally, where some 28,500 American troops are stationed to protect the country from its nuclear-armed neighbor to the north.

South Korean conservative President Yoon Suk-yeol, who came to power in May, is seeking to strengthen this military alliance after the failure of attempts at diplomatic rapprochement with Pyongyang led by the previous government.

"This exercise has been prepared to demonstrate the strong will of the South Korea-US alliance to respond to North Korean provocations," the South Korean navy said in a statement.

The exercises, lasting four days, mobilize more than twenty ships, including the American nuclear-powered aircraft carrier USS Ronald Reagan, as well as significant air assets.

They will consist of naval combat and anti-submarine warfare simulations, tactical maneuvers and other maritime operations, the navy said.

These exercises start the day after a ballistic missile test by Pyongyang, the latest in a long series that began several months ago. North Korea, under international sanctions for its weapons programs, also adopted a new doctrine in early September proclaiming that it will never give up nuclear weapons.

Washington and Seoul have long conducted joint military exercises. Both allies insist on their purely defensive nature, but North Korea sees them as dress rehearsals for a future invasion of its territory.

Last month, the United States and South Korea conducted their largest joint military drills since 2018. Those drills had been scaled back due to Covid-19 and a now-over diplomatic warming between Seoul and Pyongyang.
