The pipeline was laid in pieces by a ship designed for that purpose. Obviously all they'd need to do is send the ship out there and take out the damages sections and then replace them.

Notice how he glosses over that "There are technical possibilities to restore the infrastructure" because he doesn't want to talk about that, HIS priority is to talk about who did it: "As of today, we proceed from the fact that it is necessary, first of all, to figure out who did it, and we are sure that certain countries, which had expressed their positions before, were interested in it. Both the US and Ukraine, as well as Poland"

This is exactly what I would expect if Russia blew up the pipeline themselves in order to play the victim and rally domestic support for the regime by pretending to be under attack.

Hey, people are mad about this whole conscription thing, what are we going to do about it?

THEY BLEW UP OUR PIPELINE! IT'S A GLOBAL CONSPIRACY AGAINST MOTHER RUSSIA!

nice one, we distract with a false flag attack, right out of the FSB playbook comrade.
