It is not just Russia. Are you aware of the SCO? Russia and CHina have formes a military alliance. They manufacture arms together and have been selling subs to Iran and other arms in the region. Pakistan and India have been flirting with joining and the Russian subs that are on the way for "war games" are doing so with some Indian involvement I believe. Take on Russia alone and win? In a nuclear exchange no one wins. IN a conventional battle of course we win. Take on Russia, CHina, Iran, and maybe India also? Do you really think we could win?
