Balalaika can declear war on anything she wants and with her ex special forces team members can win.
What did Revy say? Balalaika would give up sex before war.
I love it when she took the Yakuza's gun away and made fun of it...than killed them with it and walked out past all the Japanese police and got into her waiting Mercedes like it was nothing. When the cops tried to stop her she just told them to get the F out of her way.
