Cranston, the answers are too simple for most people to even consider, but since you don't know, I will answer. Question 1... conventional. How could you not know that? Note that no one responded, despite the clear military superiority of the US and NATO.
Question 2... No. Not unless there is a full-scale war that it is losing. That's the point. No side will lose a conventional war. 
Question 3. Because they are self-evident to anyone who can read above a grade three level.
