Step-by-step explanation:
The statement that killing hundreds of millions of people makes an agreement possible where there was no agreement possible before is incorrect and misleading. It is important to note that mass killings and violence generally do not create a favorable environment for reaching agreements or fostering peaceful resolutions. Instead, they tend to deepen divisions, fuel grievances, and further entrench conflicts. Sustainable agreements and resolutions are more likely to be achieved through dialogue, negotiation, diplomacy, and a commitment to peaceful means of conflict resolution. It is essential to prioritize peaceful and constructive approaches to resolve disagreements and conflicts rather than resorting to violence or mass killings.
