Why doesn't Russia give advance warning when using hypersonic missiles? The goal of war is to make your enemies surrender and to take their resources. If they are destroying infrastructure then they want control of the land. They can't control the land if it is occupied. Their perceived enemies must flee, surrender or die fighting.
