Why has the ICC's application for arrest warrant against Netanyahu caused such a major controversy?

The warrant still needs to be approved by a panel, it could be refused. True, it creates a precedent, but as in all trials, Netanyahu is innocent to the last degree of guilt. I mean, just think of the worldwide news of the arrest warrant, only to be completely reversed say a month later. The world would talk about this for weeks and would polarize commenters. The world needs stability, they cannot say such a scandalous news then return to normal. Put this way, it’s not possible.

For me, ‘til it’s approved, this warrant reflects merely the evaluation of a single man, not the completion of ICC judicial process.
