War is war, and it includes whatever the warring parties deem necessary for a favorable outcome.
There is cold war, hybrid wars, hot wars, conventional wars, regional wars, world wars and nuclear wars.
Apples and pears are bot fruits. Still they are different.
When a hybrid war is made to to costly a hot one is the consequence.
And when you are peaceful, like Russia, a hot war might be necessary to stop a warmongering nation like Ukraine.
