I'm sure ISIS has/had reasons for what they do too if you look at it from their perspective.
Aye, ISIS too has motives that must be understood.
If one dismisses them without consideration, then
this is aggressive ignorance that will defeat any
possible solution to stop the violence.
This could explain the common comparison that
Israeli apologists between Hamas & ISIS. This
intentional refusal to understand the fundamentally
different motive serves only to demonize Hamas,
& refuse to give Palestinians justice.
To have peace, one must want peace.
It is up to Israel, the far far greater power that
makes the law, & oppresses Palestinians, keeping
them destitute & corralled. The greater power
bears the singular ability & responsibility to pursue
peace & justice. Think of USA vs Indians pre-1900,
& Putin vs Ukraine.
