I agree with many of your premises, but not the main one. People are brainwashed for sure that migrants, jews, muslims, etc are the problem, but they do have grievances that the state does not care for them. Blaming Putin on that perception is silly, he wish he was that powerful. US had for decades massively aired propaganda in all corners of the world, financed NGOs, payed journalists and the results were mixed. Putin does not employ not even a 5% of the US budget into those operations. Farage is a good example, he noticed that the British are not happy, that Brussels was getting more powerful and blamed all in Brussels with memes like curved bananas etc (I know trade and knew Brexit was horrible for both side of the Channel) but I don’t blame Putin for Farage or Trump… they both are just opportunistic in a situation those countries fail to deliver. UK and US are both in a worse situation due to these two politicians, but banning them both would have been far worse since the discontent still unaddressed. Blaming in Putin for them both is just ridiculous, he wish he had that power!
