Again, the racism in the UK and elsewhere is one problem, Putin’s misinformation campaigns are another. These are two different things. (And, again, not all are racist in the UK - or in any country - as we can see, for example, with the ‘Rwanda deal’ you mentioned as this very deal is history now.)
That’s a too simplified abstract of what the article is about. It’s not that Russia made the racist far-right in Western Europe and elsewhere (the Putin regime appears to provide some funding to European right-wing parties, though, as we have seen in Germany’s AfD, for example), it’s that Putin fuels that sentiment. The Russian government tries to actively destabilize the societies, that alone is a violent act and by many considered an act of war.
(And, no, Britain is not “racist AF”, some people over there are racist. We should not pidgeonhole a country, neither Britain nor Russia.)
[…] called quantum technologies “potentially revolutionary and disruptive” and classed them as “an element of strategic competition” with rival states […] for components that can have military as well as civilian uses [and potentially] give China a scientific and military edge.
So the article is quite clear, just read it.
Basically, it is what China has always been doing, too. Many argue that China has even harsher rules regarding international collaboration -in both science and economy- and does not show any willingness for reciprocity.
What has the police’s reaction here to do with Russia’s disinformation? It’s just about raising a new issue to point the finger to anywhere else.
