US flies warplanes over Korean Peninsula amid N Korea tensions

The United States often sends powerful military aircraft in a show of force in times of heightened animosities with North Korea. The North launched its latest missile as it protested against tough new UN sanctions over its sixth nuclear test on September 3.

Monday's flyovers over the Korean Peninsula involved two B-1Bs and four F-35Bs from the US military and four F-15K fighter jets from South Korea, according to the South Korean and US militaries. The US and South Korean planes practiced attacks by releasing live weapons at a firing range in South Korea, the US Pacific Command said in a statement.

The US warplanes also conducted formation training with Japanese fighter jets over waters near the southern island of Kyushu, according to the Pacific Command.

Since Kim Jong Un took power in North Korea in late 2011, his nation has tested weapons at a torrid pace. The country flight-tested two intercontinental ballistic missiles in July.

Its nuclear test in September was its most powerful to date.

Many experts say it's only a matter of time until Kim achieves his stated objective of possessing reliable nuclear- tipped missiles capable of striking anywhere in the mainland US.

State media on Saturday quoted Kim as saying that North Korea's final goal "is to establish the equilibrium of real force with the US and make the US rulers dare not talk about military option" for the North.

Alarmed by North Korea's advancing weapons programs, many conservatives in South Korea have called for the reintroduction of US tactical nuclear weapons in the South.

But the liberal-leaning government of President Moon Jae-in said it has no intention of requesting that the US bring back such weapons.
