1) no thats not the case, you're making an assumption that the launch platform will only launch from within sovereign spacethe strategic implication of air launched ICBM are immense. they are
1. the platform will always be in the states own airspace
2. SAM system cant target these platform as they are outside there range
.3. they are immune to any first strike nuclear attcks
4.they can be on a constant patrol in the states own airspace thus avoiding detection as there is a chance of ssbn to be detected on patrol at high seas
5.they are in constant linked mode that allows them to perform a retaliatory strike immediately
2) incorrect, SAMs are also part of the broader COP where they are but a node in the sensor space, the SAM can and do get targetting feeds from other COP elements. That includes TACOP/SACOP
3) no they're not
4) incorrect, OTHR, SWR can and does track aircraft - including some generations of VLO in any space
5) how and where is the evidence
I'd suggest that you not make claims which are not accurate and present them as fact - especially when some of us in here deal in COP and track management capabilities.
