I'm really not interested n how "difficult" it is to do the right thing. Either you do it or you don't.

I'll quote a bit you didn't in your desire to wave away any suggestion of wrongdoing:

"CNN found that, not only did the forces fail to stop the riots in Huwara, they did not protect residents as settlers set fire to Palestinian homes and businesses and blocked emergency services from responding. Instead, when residents threw rocks in reaction to the settlers’ aggression, Israeli forces fired at the Palestinians with tear gas and stun grenades..."

I would say that firing at the Palestinians is supporting the settlers.
