It Is Already ...

... happening and the only issue are purely operational and even tactical details. Russia will destroy Western support for Kiev’s war machine – Lavrov: 

The minister said Moscow would not resort to the same tactics, but warned that its response would become increasingly severe. “We will not sink to their level. Instead, we will adopt much harsher methods to destroy everything that enables the West to fuel Kiev’s war machine. We are already doing this, and they are already moaning.” he said. The minister also reiterated that Ukrainian and Western proposals to freeze the conflict along the current front line are unacceptable. He argued that doing so under present conditions would amount to betraying both the Soviet victory over the Axis powers in World War II and the broader history of Russian statehood.

Russia doesn't do terrorism, West does. Some elaboration on semantics is due, though. "Kiev's war machine" is NOT Kiev's, in general it is NATO's "machine" which has been severely damaged during SMO and now that Odessa and Nikolaev are isolated--the work continues to make the Black Sea a Russian lake--the choking of the railroad network is also in progress. The bridge in Mayaky is now being pummeled for three nights in a row and it will be destroyed. 

Here it is in a larger scheme of things. 

So, Odessa is going to be strangled. Here are some visuals from Kiev's, a capital no less, a grocery store. 

This all is the result of what Russia is doing in terms of final strangulation of West's beloved Nazis and at some point, which in near, Russians will repeat an old English saying to Irish--we hate you for what you made us do to you. 

Lavrov also reiterated the warning, saying the Russian Navy could begin “focusing on the ships serving countries which have made pillaging and piracy their official policy.” In case of French or British, or Dutch commercial traffic which Russian Navy will choke off in the Pacific, this saying will not be used--Russians hate the West simply because of what it is. But yes, they can really make Europe miserable and then, maybe, send couple of Il-76s with humanitarian aid. Just to show that Russia "cares" if you know what I mean.
