Comments like this one are the gears that turn to prevent peace. As with many conflicts, both sides do things that are incompatible with peace, and will not give them up because they see what the other side does. The answer is not to blame one side for reacting to the other.

It's not a novel situation at all. There are well-established, well-studied ways to build trust and peace.
