As usual the waters are very cloudy and without somebody fessing up this will always be conjecture, and the moment you say to yourself so and so had no reason to do this, there is your reason, and if you say the other so and so’s had every reason to want this stopped, then it affords the opposition a chance of a set up or you as internet sleuth and glory boy as being duped/not aware of all the machinations, add in your bias and you are tail chasing.
So here goes, the case for it being Russia seems to hinge on them being bastards, they are clearly the aggressors, eat babies and care nothing for dolphins.
But IT was their pipeline that could at sometime have netted them a lot of cash, why do it? To implicate the NATO, ergo it was the Russians.
NATO/US, the case for this; Two presidents had voiced opposition to Europe being beholden to the Russia for fear of waning influence in the region as all Americans know that Europeans are all homosexual communists at heart, Europeans know that the US will not brook any diminishing of their outright domination of NATO so work in other ways to nibble at the roots. No citizen of the free world would suspect the US of such a blatantly hostile act in the waters of an ally, fuck yeah, it was the Yanks.
Things to bear in mind.
Nearly all US citizens are aware of some shady and nasty things done in their name, but they know in their hearts, because they live amongst lovely people who help each other out and care for their children, that America isn’t nearly as bad as the Homo-communists make out.
Nearly all Russian citizens are aware of some shady and nasty things done in their name, but they know in their hearts, because they live amongst lovely people who help each other out and care for their children, that they aren’t nearly as bad as the Homo-fascists make out.
Conclusions? It was either the US or Russia, wait 50yrs, if we are not living in the ashes of civilization then it will come out, maybe.
