Way to avoid the question

I'm not avoiding the question - you are avoiding the entire reality of the situation. The colonized does not require your approval or oversight to wage war against colonizers.

devising a workable solution to the inherent complexities that exist between the two countries.

What complexities? Why are people all of a sudden pretending that western colonialism - and the resistance against it - is suddenly a "new" thing?

(the impetus for which I can only guess)

Again... there is no mystery here - Israel has always been a western-backed colonialist project. No ifs, ands or buts. Where is the mystery?

but escalation via killing uninvolved civilians

If we cared about "civilians," wouldn't we be concerned about colonialism in the first place? No? Then I guess we're only concerned when said "civilians" belonging to the colonizer side start dying, eh?
