One might be a coincidence.
Two out of two? Considering how few high profile whistleblowers there are, that is much more unlikely to be due to random chance, statistically speaking.
Similar to how it's not impossible that someone might fall out of a window and die.
But if in a certain country, important people who have crossed the leadership keep falling out of windows, ... well.
That's literally not how it works, anything else is Russian fearmongering.
Also a bunch of countries fucking up a single country who can't even conquer their neighbor does not a world war make. If it did, the Gulf War would be called WW3 already.
