> That is a very particular use of the term 'escalation' which is bound to mislead people.

I am not the OP, but I think your interpretation is not as obvious as you make it to be. This often leads to misunderstandings.

AFAIK military analysts use the term escalation as a morally neutral term. Escalation is anything that goes up on the 'scala' (= "ladder", the Latin root of the word). In this interpretation, D-Day would be an e_scala_tion (climbing up the ladder) simply because opening a new front means number_of_fronts_today > number_of_fronts_yesterday. In this interpretation, self-defense and escalation are not mutually exclusive.

Apparently, the term changed meaning. Many people now treat it the way you do (if I understand you correctly) as something associated with aggression. Therefore, they assume that when someone labels something like an escalation, they mean it is an act of aggression, unjustified, something you should not be allowed to do, and not morally neutral.

I am not saying you are wrong. I am just pointing out that when people talk about escalation, it is worth checking whether they mean the same escalation.
