ARPNET didn't turn into what it is today because of military usage, and OGAS didn't fail because of it's resource management use. They lived or died because of money. The United States and Soviet Union both had to build all of the precursors and fabric that these systems would run on (telephone lines, computers, etc), which both did. The next logical step was for computers to co-opt existing national infrastructure and create a national network of computers. The Soviet Union faltering elsewhere is why OGAS didn't develop and ARPANET did.
