That's about as logical as saying that the moon must be made out of cheese because the NASA came back with moon samples and they weren't cheese.
You'd get on well with my boss. He loves his conspiracy theories, his best friend is German, and one of the biggest bullshitters going.
When he can't win an argument, this German resorts to all the old tactics of changing the topic of conversation, picking up on points that have nothing to do with anything.
At work he ends up talking with this woman who's also into her conspiracies, you can't get a word in edgeways, and it doesn't matter either, because neither of them is going to listen to a damn bit of logic.
The logic is perfectly fine. They had no other use for this old agent anymore and now we have that May clown charging Russia with murder.
What does the UK gain from having some kind of proxy war with Russia? Nothing. The UK imports too much oil and gas from Russia to want to have this.
Where does UK gas come from?
35% of gas in Britain comes from Russia. If Russia were to block western Europe, the UK would struggle to get more than the 43% it produces internally, because all the other countries would want it.
Russia supplies 20% of Europe's oil. A hit that big would be a disaster for the UK and for the EU.
They used a nerve gas that only Russia makes. So, Russia either did this, or sold the agent to someone who would want to use it.
Who gains from killing this guy? Only Russia, they send a message to their own spies.
The only other plausible argument is that it's someone who wants to damage UK-Russian relations. If this had been the case, Russia would have been far more open about dealing with this, like by responding to the UK's demands. It didn't.
Then you have Putin making threats.
Then you have Putin's politicking with US elections, Ukraine, Georgia, in the former Soviet areas of the Baltic and much, much more.
He gets rid of political opponents. He doesn't care, no one ever gets arrested for these crimes, the people get killed openly, it tells Putin's opponents what to expect.
His main opponent for his job has been banned from running....
There's a pattern, you can't see because... because..... who the **** knows or cares?
