Maybe there's a glimmer of hope that someday both sides can send their robots to destroy one another, instead of their sons and daughters? I agree that initially there's an advantage to richer nations, but it's not like a $30M jet fighter, there could be parity.
That's not how it's going to work. There's no point in taking out a relatively cheap robot that can be replaced in a day, when you can take out a person that will take 20 years to be replaced.
