We have executed much more than this without getting caught.
1: For example, as something we can now talk about, FDRs totally illegal support of the UK before Pearl Harbor. A total violation of the Neutrality Act....but it stopped Operation Sea Lion, and saved the free world.
2: Our very successful overflights of the USSR in the last years of the 40s, well into the 50s, just to pizz off the Sovs. We would launch B-45s from the UK, direct Moscow, direct Kiev, then back to the UK or Italy, just to show the Sovs they could do nothing about it.
BTW, the AF would always arrive over the Kremlin at exactly 12:00 Moscow time, just to twist the Central Committee’s tail even more strongly.
3: Then their was Operation Vestibule....
Time has a way of excusing certain acts when the ends are achieved.
With all respect, what would you all have done to stop Tojo or Hitler in 1938?
Do you take Kim’s threats seriously. I do.
Would you now do the same to stop Kim?
Not sure that lends merit to your proposition. Redirecting a missile launch to strike within the US would be much worse than intentionally not directing US military command in Hawaii in 1941 to prepare for an immediate strike by Japan.
It may not have been clear from my post but I appreciate your concern about the situation and your attempt to generate an action plan instead of sitting passively to see how things turn out. My post simply suggested there is probably a more effective way to use the essence of your proposition: that we could likely redirect a NK guidance system (of which I am somewhat confident, either before or after launch).
My proposal would remove the source of the problem without damage to the US, and without a serious risk of starting WWIII.
