I do not mean to be argumentative procedurally, but the proponent of an argument must have the burden of proof. Aggression means something more than moving chess pieces about the board, it must mean something like invading Georgia, Chechnya, Crimea, Ukraine to be meaningful.
What aggression toward Russia would you have America knowledge?
