The same could be said of nukes. Why would Russia or China or anywhere spend billions of dollars on developing, researching and building nukes when they aren’t being used or likely ever be used in war, let alone win any war, ever?
Oh that’s right. Countries develop nuclear weapons as a deterrent, not as a means to use them.
And that’s the point of having a well armed, well stocked army.
Looks pretty cool. We gon be livin on da moon.
