Our military works to terminate connections in command and control, which then allows us to terminate enemy forces while minimizing civilian casualties. The enemy (like the chicoms, etc.) are not so surgical, they seek total devastation regardless of civilian casualties. And no, a nuclear tipped cruise missile is not avoidable if it makes it to within a certain radius for detonation.
Understood, but I have read you have about 15-25 seconds to detect and react to it, as it flies under radar. i think Iran has them also. Persian Gulf has some tight quarters!
