"U.S. Adds F-22 Fighter Jets To Military Exercise In South Korea" By: Sydney Magnall

The U.S. sent two  F-22 Raptor fighter jets over to south Korea to take part in military drills. This move is supposed to show the Commitment the United States has to the defense from North Korea. The President of South Korea gave permission to the country to strike back at north Korea at any point. The New york times says,  Park told the South's generals that she considers the threats from North Korea "very serious." "If the North attempts any provocation against our people and country, you must respond strongly at the first contact with them without any political consideration."As top commander of the military, I trust your judgment in the face of North Korea's unexpected surprise provocation," she added. 

The threat from North Korea seems very serious and I hope South Korea is protected.
