And it was not a war crime for the allies to attack bridges and rail hubs / marshaling yards all across western France in the months leading up to the invasion in Normandy; these attacks were perfectly legit.
Most of the codices regarding the conduct of modern warfare were not created until after WWII.
Thus, doing so today is not a war crime.
The ICC has prosecuted numerous charged war criminals. International war crimes warrants exist today for both Vladimir Putin (March 17, 2023) and Benjamin Netanyahu (November 21, 2024). Neither Russia nor Israel signed and ratified the Rome Statute. However, this does not relieve these individuals of responsibility and they can be tried in absentia.
if all you can do is scream "war crime!!" and have no capacity to enforce it, your screams don't mean anything. The legal reality is international law in enforced by those with the physical power to enforce them.
The ICC does not have jurisdiction in all territories of the world. Countries such as Bahamas, Cuba, Chile, Haiti, Jamaica, St. Lucia, Grenada, Guatemala, Nicaragua, El Salvador, Suriname, and the United States signed the agreement in the first instance, but did not ratify their adherence to the final treaty. China, India, Israel, Turkey, Pakistan, and Russia, are among 60 other countries that openly reject the interference of the ICC in their territories.
The US is not party to the treaties which created the ICC and thus is not under its jurisdiction.
As I noted in Post #99.
The US is not a signatory to the Rome Statute.
