I can't even begin to make any sort of judgement on that, there are multitudes of mechanisms at their disposal I'm surely unaware of that could be employed. Netanyahu may be suffering his own consequences at home without help from the outside, creating a setting for the ICC in the near future to come after him in a different way with fewer potential pitfalls, though again I can't say what should be done. I can see the author's point in how this action could potentially not lead to peace right now, and agree.
