What you say may or may not be true, but it is beside the point. The point is that the USA, or any country, has the right to deny it's airspace to anyone. There is no rule that just because we let it fly through Montana that means the USA has to let it fly anywhere. There are all kinds of instances of the USA being denied use of another country's airspace. I'm not quite sure on the exact situation as it was a while ago, but I think during Gulf War I, or maybe II, Turkey would not let the USA take off from Incerirlick Air Base to bomb Iraq. Ah, here it is,they closed their airspace for a while in Gulf War II - https://www.theguardian.com/world/2003/mar/20/iraq.helenasmith https://www.theguardian.com/world/2003/mar/20/iraq.helenasmi... It seems like you are giving China a pass to me. >If it was a serious threat to US national security, it would have been blown up over Alaska Nope. USA has the right to do it anywhere. We don't know the strategy. Maybe there was some global strategic reason or tactical reason, or who knows? Neither of us is the Chairman of the Joint Chiefs of Staff, or are the Secretary of Defense. What do we know? All I know is that the USA can shoot down any aircraft, at any time, for any reason, if it doesn't file a flight plan and let the USA know the purpose. That I know. But you saying "If it was a serious threat to US national security..." is silly. You are not the Secretary of Defense. How would you know? Or anyone know, unless privy to that information? That's how it works.
