What was that about the mierda and the ventilador?

Russia is fomenting divisiveness globally.

Resentment toward Madrid dates from at least the Franco dictatorship, when his forces (with Hitler's help) brutally squelched a separatist effort in the 1930s - and afterward spent 40 years sucking them dry in order to bolster his own region (the most conservative and backward in Spain), Galicia.

The post-Franco constitution and other reforms mollified separatist sentiments for a while; but Spain's collapse in 2009 - and Rajoy's trickle-down dogma - has no doubt done a lot to revive them.

The final straw was the thuggish attack on the 1st of this month (see footage above). Over 800 injured.

Basically, Rajoy's going full-Franco on them - and that, you do not do.

And its lack of support for Catalunya.

This is consistent. Overall, Russia opposes shifting borders.

Russia becomes less consistent when the shifts in borders benefit it directly. But to support Catalunya would be to license support for potential break-away regions in the Russian Federation and justify the breakup of the USSR.

It pays to note, however, that in many ways Russia prefers that Russian minority populations stay in their current countries--that gives them leverage over those countries. You get them openly supporting S. Ossetia, Abkhazia, Transdnistria, and the Donbas when those populations lose their disproportionate importance in a nation-state that's increasingly "fascist" (meaning 'anti-Russian') and so then the fall-back position is open disruption of the nation-state that those populations were part of.

Rumors are and have been that Russia will simply annex S. Ossetia and Abkhazia, but those rumors are like the undead. No matter how long they're around, they're still around; and no matter how many times they are buried, they dig their way back to the surface. Eventually, perhaps, one will finally be right.

The Crimea is a blatant exception to this, but rhetoric in Russia had long been it was part of Russia and, well, the naval bases there were just too important to let expiring contracts put at risk. Nominal independence as in Abkhazia would have been problematic and been a thorn in Russia's side in ways that simple annexation by fictive vote would never be.
