It's a long piece of text. Where do you see, in particular, an actual reference to restoring the previous USSR borders?

> Peter the Great waged the Great Northern War for 21 years. On the face of it, he was at war with Sweden taking something away from it… He was not taking away anything, he was returning. This is how it was. The areas around Lake Ladoga, where St Petersburg was founded. When he founded the new capital, none of the European countries recognised this territory as part of Russia; everyone recognised it as part of Sweden. However, from time immemorial, the Slavs lived there along with the Finno-Ugric peoples, and this territory was under Russia’s control. The same is true of the western direction, Narva and his first campaigns. Why would he go there? He was returning and reinforcing, that is what he was doing.

> Clearly, it fell to our lot to return and reinforce as well. And if we operate on the premise that these basic values constitute the basis of our existence, we will certainly succeed in achieving our goals.

Returning and reinforcing means restoring the USSR or Russian Empire's territory to Russia.
