There is no doubt that Putin wants to destabilize the “West” in any way he can, on the other side we have done a lot to harm Russia’s interests over many years.
I would separate that from donations to the Tory party, that is just to enable Russian oligarchs to launder their dodgy cash in the UK. That’s for personal gain rather than national interest.
I’m concerned that Johnson and Cummings have Russian contacts, the fact that they have used populist or nationalist tactics to win an election is no more than other UK politicians have used in the past. Will they use these these contacts to give favour to Russian interests in the Brexit trade talks - probably. I remain to be convinced that that Russia is a threat to democracy in the UK, although Cummings could easily be an agent at the center of government and it’s just a crazy risk and he shouldn’t be there.
The connection to Covid 19, they are all careless with lives and try to put financial and economic interests first, they have failed spectacularly in that. The original package of loans and deferred taxation has expanded beyond their worst projections.
