Air Force, flew over South Korea, U.S. military build-up around China aimd Korean Peninsula tension

A formation of F-22 Raptors, the most advanced fighter jets of the U.S. Air Force, flew over South Korea on Wednesday, a latest show of force against the Democratic People's Republic of Korea (DPRK) over its nuclear test and satellite launch.

Also, naval power is to add to reinforcements as the nuclear-powered aircraft carrier USS John C. Stennis will participate in an annual U.S.-South Korea military drill next month.

The United States is increasing its military force deployment in and around the Korean Peninsula after the DPRK claimed that it had conducted a successful hydrogen bomb test on Jan. 6 and a long-range rocket launch on Feb. 7. But does it mean that the United States will launch a war against the DPRK?

Although the White House warned in a statement that the DPRK's actions "is a threat to the United States," weapon experts said there remains little mortal security threat to the country as Pyongyang has not any missiles that could reach America.

Also according to the Pentagon, the DPRK's KN-08 intercontinental ballistic missile, which is capable of hitting much of the United States, has not been tested yet.

What's more, Washington has focused more of its attentions on Syria, as both Vice President Joe Biden and Secretary of State John Kerry have mentioned possibilities of lifting military operations against Syria in the coming days. Thus it's unlikely for the United States to launch another war on the Korean Peninsula.

Actually, for the U.S., the reason to deploy THAAD is not only to target the DPRK, as Pyongyang could never become an imaginary enemy of this defense system.

First, THAAD is one of the most advanced missile defense systems in the world but falls short of shielding South Korea from hundreds of shorter-range the DPRK's missiles that can fall on its entire territory in several minutes. Thus, the deployment will not offer Seoul anti-missile security.

Secondly, as Washington claimed, the DPRK's missiles could not reach the U.S. homeland, THAAD is absolutely not focused on defending the U.S. against missile threats from the Asian country.

In fact, the strong early-warning ability and the extended monitoring range of the system will help THAAD monitor missile activities of countries far beyond the DPRK.
