Earlier quoted context omitted.
He very vocally defended Russia while they were building up to the invasion and then became completely silent after they invaded. I wouldn't be surprised if Snowden doesn't actually have the password to his Twitter account and can only post Putin approved tweets.
A lot of people, including establishment "experts" didn't think Russia was going to invade and called US estimations war-mongering. Also it's probably not a good idea to antagonize the people holding you hostage, he's one hospital trip away from falling out a window. Snowden is clearly trying to be as effective as he can in spreading his message, given his conditions. He's already sacrificed any semblance of a normal…
And they were all proven definitively wrong, the only war mongerer is Putin, who just escalated his invasion of Ukraine by ordering a partial mobilization. If you think that the GRU doesn't have the password for Snowden's twitter then you are very gullible.
