The US Defense Department has ratified the sale of advanced stealth fighter jets to South Korea amid escalation of war of words between Washington and Pyongyang by PressTV

The Pentagon said on Wednesday it had notified Congress about the possible sales of new military hardware including two competing fighter jets — the Lockheed Martin Corp F-35 stealth fighter or Boeing Co’s F-15 Silent Eagle fighter.
The sales would also include new radars, electronic warfare systems and other equipment, it said.
The Defense Security Cooperation Agency, which oversees foreign military sales, said that the US fighter jets would help South Korea “deter aggression in the region.”
Seoul, which is expected to announce its decision about the purchase of 60 fighter planes later this year, should choose between the F-35, F-15 and Eurofighter Typhoon.
War of words escalated between Washington and Pyongyang after the participation of nuclear-capable US B-52s and B-2 stealth bombers in ongoing joint military drills with South Korea.
On March 11, Seoul and Washington launched their annual joint military maneuvers near the Korean Peninsula despite warnings from Pyongyang. The drills involved 10,000 South Korean soldiers and about 3,000 US troops.
