The strikes are only pre-emptive if we put on white-nationalism glasses and take away Lebanon’s right to defend itself. Israel attacked Beirut first.
I guess as always with language, there are many possible interpretations. Yours is one, that’s right.
To me, it came somewhat surprising to see you connected “pre-emptive” to moral judgements, or to the question who attacked “first” (which is a controversial and potentially infinite topic to track the actual honest true ‘first’ origin).
Another interpretation is just military doctrine. The best defense is a good offense. Who cares who started the fight.
In this interpretation, the IDF felt there might be an attack incoming, and prevented it’s adversary from doing so by striking first.
Much like Hezbollah (or any other military force) would gladly pre-emptively strike their foe to protect their own troops. Doesn’t say anything about who started the overall conflict or even who’s right.
You still have a point; by highlighting the reasons behind the strike, and painting it as a protective measure, it probably makes it easier for the reader to sympathize.
