They basically want a war that uses a trillion dollars in military equipment with hardly anyone dying (although some want the deaths too, I don't doubt). I think that's the dream for many weapons manufacturers.

If we ever have robot wars, they'll be making so much money. Imagine China's bots vs The West's bots in Afghanistan. Imagine $100 million of robots getting destroyed by each other everyday in the middle of the desert, for years. That's like Boston Dynamic's wet dream. And "the war can't stop or else the enemy robots will be able to invade human areas and people could be killed" will be the justification. So it's for "safety". And thus this never ending robot war will be in a stalemate for years and years, scaring the crap out of everyone while making those in charge trillions of dollars. Until someone hacks the robots perhaps... sounds wild but I could see it happening, given the incentives involved.
