"These flyovers, air demonstrations and static displays, including the landing for the B-52 on the peninsula, are part of our continued pledge to promote peace, stability and prosperity on the Korean Peninsula," U.S. 7th Air Force spokeswoman Maj. Rachel Buitrago said in a statement released by U.S. Forces Korea.
Ah yes, nothing says "pledge to promote peace" like flying a nuclear-capable bomber as a show of force.
