Contrary to hysteric media narrative, decision makers in Kremlin are not mad, crazy or whatever, and believing this brings more harm than good. Russia isn't strong enough to seriously threaten Western Europe, and they are aware of it. Moreover, they have not much to gain by trying to conquer Lisbon versus monstrous costs they would need to bear, even if we ignore the fact they wouldn't be able to not only reach Lisbon, but Berlin as well. Europe is no longer a center of the world, regardless if we like it or not.
That doesn't mean Russia cannot harm interests of countries of Western Europe, carry out sabotage acts, sow and fuel internal strife etc. They can, and they do. But it is not an existential threat.
