I’m not saying we should rely strictly on that.
Like I said, we need to stay a step ahead militarily as well. Right now we’re a mile ahead.
This is comparable to you having a Rolls, two Bmw’s and a Ferrari in the garage, and feeling threatened by your neighbor who never had a car, when he suddenly buys a toyota.
If we want to stay ahead, we would divert all our money away from carriers into robotic ships with robotic planes.
