@king_stranglehold_da_first: No one wants to fight Russia. Too big, too cold and their military is quite tough, but it certainly doesn't make them a superpower. A battle on Russian turf only gives Russians a home field advantage, but on neutral grounds?
IMO Russia is a regional power based off the definition:
In international relations, a regional power is a state that has power within a geographic region. States which wield unrivaledpower and influence within a region of the world possess regional hegemony.
Israel and Turkey are not regional powers because Iran and can take either of them on imo. For Russia to be a superpower like the USA it would have to have military bases around the world; along with being able to invade any countries, no matter how far they are. Whether they win or lose, the USA has the capability as a superpower to invade Russa. Russia on the other hand can't invade the USA(doesn't mean USA would automatically win in a war against Russia). That's one of the perks in being a SP. Again this is just my opinion. I could most likely be wrong.
@superguy1591: What makes you think that Russia isn't the superpower Putin and everyone in the wolrd says they are? I mean they have displayed it more than once through the years and they can prove it again to the wolrd. I don't think that either the USA or China are even close enough to the fire power Putin has but I am open to see your argument.
Nobody in the world says Russia is a superpower. Its a best a regional power.
From what I read Russia is the second strongest country in terms of military might. I'm going with Russia. Not only that I don't even think the UK has the manpower to conquer Russia. As far as round 2 Russia has enough(more than enough) to devastate the UK, which is just an island.
