and is an aggressive nation
Who told you that?

Russians have never been "an aggressive nation". It seems like you've heard too much about the "Russian agression"...
The Russian nation is quite peace loving. We always lived in harmony with many nations. Some of them entered into the Russian Empire of their own free will (like Georgia, by the way).
As for the Russian conquests, like Tatarstan, the Central Asia, and others - they are conquests of tsars. It's normal, all the rulers in all coutries were alike, and it doesn't mean that the nation is agressive. The tipical Russian мужик has a very patient character. And the nation has always been very patient.

We are strong (the State is strong), but we are not agressive. It's not the same.

It seems like you really know few about the country which, or rather whose politics, you "love".
