No, that is the only thing that makes the ICC justifiable under the anarchy of international relations. If a leader of a nation unilaterally revokes the treaty submitting themselves to the ICC's jurisdiction, that's a harder case, and I'd support the ICC going after that nation's citizens if they commit other offenses.
But if a nation decides not to submit to the ICC, then it's up to the UN Security Council to go after them, and the Security Council was set up intentionally to only allow punishment of leaders where every major power can agree. The Security Council at least tries to work with the reality of international relations, whereas the ICC in this case is way out of line.
