I heard there is a term (paraphrase) Allow first missile strike. This means an incoming missile is allowed to hit its target. Why? Every nuclear missile has its own identification pertaining to what country makes it. There are military planes up constantly sniffing the air. Nicknamed sniffers. If say a missile was launched say by France at the USA and it was expected it would be from China, the US Military would allow that a first strike, establish who sent it and retaliate immediately. This stops an innocent country being blamed and wiped out thru a rogue missile launched by ??. Can you remember when AF1 had a missile launched at it when 45 was on his way to North Korea, it is believed it was from a sub near Whitby Island. Anons asked how was it shot down? Q replied a modified F16 or an F? I cannot remember the number. Same off Hawaii. They also had a missile launched but while there was banter it was North Korea, they knew what country probably launched and it was the DS.
