but I promise you every government has strategic documents going through different scenarios, including the usefulness of war crimes to achieve goals.

I disagree here. I cannot prove it, but I can give you my honest informed opinion: I know that there are governments that do not stoop to that level. Sometimes, a country gets a government that does this, but then it gets another government that is more civilized and moral and scraps all this.

There are governments and people leading these governments that are actually committed to not do these things.
