The motivation (esp for Germany) to build energy trading relationship with Russia - aside from it being jolly convenient - appears to be the belief that this would stabilise Russia / EU relationship. Based on the assumption that countries that have critical trade with each other don't tend to go to war with each other. Instead, Putin is leveraging the reliance on gas to try to mute the West's response to the invasion.
Some persons use the same motivation to stay with their abusive partner. The problem is it seldom gets any better but it mostly gets worse, because you give the abuser or abusive country in this case more leverage, something to overpower you, or in this case nato/eu You would expect them to know better. At the very least they could have set conditions etc.
Putin has been wanting to sideline the US in global politics and fracture the EU for many, many years. For nearly a decade, Putin and his chums have been pouring in dark money to further those aims and you can bet that Brexit was a key part of this. Even the intelligence report commissioned by the Trump administration said as much. The UK report into Russia influence was pretty conclusive that "Russian influence in British politics was commonplace". Funnily enough they didn't find evidence of Russian involvement in the Brexit campaign. Why? Because the scope of the report specifically didn't authorise investigation relating to Brexit. I wonder why
''Dark money'' that's the strawman, laterly it his been upgraded too ''they all put their money in crypto currency'' which is ''uncontrolable'' so ,maybe in about 1-3 months time their will be widespread calls to control crypto currency, which off course won't hurt the real dirty money but will hurt normal transactions.
You know if you look at the other side, thankfully the still reachable from the uk rt news for a consistent time you start to recognise paterns, surely i don't beleive any of their ''special opperation'' ''Ukraine are all nazi's'' BS but in a way they say the same as the ''dark money'' strawman, where we say dark money they say ''the west'' but the idea is the same.
But the main picture is a bit simpler, Putin is intrested in his main threats that are the Us and Nato, the eu and uk also long before bexit have been infiltrated so far that they are on itself not longer a threat to him, more like a toy. And that is what we saw once again today, the Nato came with an statement ''we are ready'' but could'nt go much futher as letting 2 b52's fly along the Ukranian border.. The Netherlands did the same with Germany during the second world war, and when germany finally invaded it took them less than a weak.. turns out being ready puts you always on the backhand if you enemy can choose the moment of attack.
You shouldn't always strike first but when the enemy insist on war, maybe start by taking away the abilty to wager it, that's what an no-fly zone in part would have archieved.
