This is a daft comparison. It's like comparing the number of arms of the military to the number of arms of a single police station. NATO is an alliance comprising multiple countries. To compare that to a single country is just plain stupid. If you want to draw a comparison then rather compare the arms of NATO to what is likely to be the Russian alliance should yhings go horribly south, Russia, China, North Korea, Saudi Arabia, Iran and several African countries. Not to mention some other Eastern block countries like Belarus. If we look at other countries like India then they are more likely to be on Russia's side than NATO even with the little tiff with China where the hit each other with sticks. India will not side with any alliance that includes Pakistan due to their history.
