Ermmmm. Which nation?Back on topic. No way some dudes from your above video in a sailboat blew up that pipeline. What a joke. It was a clear unconstitutional act of war against another nation. Just like the drone strikes of the past.
Those pipelines were not owned by a nation.
The business interests of Mikhail "Dirty Mike" Friedman, Petr Aven and Vlad Putin including their controlling interests in Nordstream were acquired with coercion and strong arm tactics including violence.
The next largest shareholder is Gazprom who needs no introduction to these forums.
Mikhail is rumored currently to be facing charges in the UK of money laundering and fraud. In Spain he is reviled due to the 77,000 tons of Russian fuel oil dumped by one of his tankers on the Galicia coast and two "raids" on Spanish companies, a technique used by the Russian mafia” with the purpose of taking over a business illegally. He got off the hook and subordinates took the fall.
I would have preferred that Germany simply close the pipelines as part of sanctions, but Im not shedding any tears for the owners of the pipelines.
