okay, well, Boroda's gettin' worked up, but some common sense:
A) Korean War kill numbers on both sides are pretty darn inflated. In order to give either side credit for their vaunted ratios, you have to accuse the other side of grossly underreporting airframe losses in their internal documents. In other words, you're accusing the militaries of lying to themselves. Now, the USAF admits to losing two F-94 Starfire Night Fighters -- aircraft so advanced they weren't allowed North of the 38th Parallel. They lost them in air-to-air engagements with Po-2s (and claiming one Po-2 in the process). If the US records will record losing their super-high-tech, afterburner-equipped jet fighters to 1920s-era biplanes, why would they underreport losing second-line aircraft to MiG-15s?
B) NK invaded. I dunno about provocation, but NK nearly got the whole peninsula. That's a pretty serious invasion.
C) There were US forces on the peninsula, but not many (a division, maybe?).
D) Most of the US aircraft in the Korean Conflict were not F-86s, and Boroda is absolutely right: the MiG-15 is unquestionably a superior air-to-aircraft aircraft than the F-51, the F-80, the F-84, the F9F, the Meteor and even the beloved Skyraider.
E) USAF pilots did strafe airfields north of the Yalu. They weren't supposed to go over the Yalu, but they certainly did.
F) The US did bomb the hell out of North Korea. After a few months, the bombers ran out of targets and went after Targets of Opportunities. There's even a case of a B-29 dropping down to 5000 feet and pickling single 500 pounders trying to hit a guy on a motorcycle. And, when it came time to get the North Koreans back to the negotiating table, they even bombed dams in an attempt to ruin the North Korean rice crop.
G) None of this necessarily means that the North Koreans did or did not have it coming to them; nor does it say anything about their atrocities.
H) The B-58 Hustler is badass!
