Mother Russia. Who is she?

[mlmaos.livejournal.com]

In the fan-works and commentaries Ivan often says "One with Mother Russia" or the variant of the phrase - "One with Russia."

I think that the reason for the joke - a historical feature of nicknames and the image of Russia.
But if this opinion can be given up - what do you think?
Who is the Mother Russia? Or why does Ivan (if he says about himself) seriously identify himself so?

Lol, Mother Russia is Ivan. Remember his epic apron? xD He is quite a careful mommy, who always ready to feed his children with some pancakes and borscht. He'll kill them, if they can't play nice though. x) (Why is this so reminds me of my mom? xD)

All mothers

Lol! All mothers are really alike!

And I think Ivan is not like when someone waive his cooking.
"Eat, I said! Eat! Or I feel hurt and kill you! Diet? What is diet?!”
