no deaths in war?

theories are capable of paving way to the future but heres a theory to end all human deaths on the battlefield

to end all deaths on a battle field humanity could always use satellite signals to control remote control machines to do battle for us and it would pave way to building better machines for exploration and if you count the fact having a gamer who excelled at ghost recon call of duty or other war games take into accounts mass effect 3 it shows humanity working together diplomatic solution and combat situations that people can use in real life so think of this have these gamers control the robots like they would in a game or simply have the soldiers suspended in a sort of virtual reality machine and they can mentally control the machine to do battle ? Also to simply give machines a sentient thought process at this moment is catastrophic for humanity because we simply cant put our differences behind us and until we do were simply not ready to create sentient machines although terminators is a good insight haha
