I don't agree with you. During the war in the Balkans as American planes were shot down? Serbia also had Russian air defense and fighter jets. Do not panic ahead of time. If we plan it right the first blow of the losses will be minimal.
The Americans are always over-confident. This can be their undoing, as even their stealth aircraft were shot down by the Serbs during the Balkan wars (using obsolete equipment). Ever heard of Zoltán Dani? On the other hand, the Koreans know that they are the under-dogs, and they are in a state of constant readiness for war.
Yeah indeed Zoltan Dani was and still is the only person perechitivay F-117, but it was an accident and not a pattern. Since that time much has changed. The Americans realized their mistake in Serbia, and North Korea's weapons remained the same. I think they have no chance.
Colonel Zoltan Dani exploited a previously unknown weakness within the F-117, and he was able to shot down the aircraft. There may be many more weaknesses of that type, yet to be discovered. The North Koreans are a bunch of very hard-working and intelligent people. My heart says that they will achieve hundred times what the Serbs achieved in 1999.
