I remember back when it was completely normal for journalists to interview the leader of a country at war, even one that is against America, for example American journalists interviewed Saddam Hussein in the lead-up to the second Iraq war, many communist leaders were interviewed during the cold war, even Stalin and Hitler were interviewed several times during the second world war.
Today, a journalist doing his job is seen almost as a treasonous act, and enough for the Ukrainian government to put a bounty on his head.
One possibility is that if all this stuff about accusing Tucker of treason turns out to be the standard political kayfabe, then this might be an attempt by the regime to reopen relations with Russia and maybe have a negotiated peace to the Ukrainian war.
If this theory turns out to be wrong Tucker may well get locked up for doing this or even assassinated if the regime doesn't have a chance to arrest him.
The modus operandi of the American empire in the past has always been to never let the enemy have a voice, the people never get to hear what the opposing side has to say in their own words, they just get to see a caricature that's only loosely based on reality, it's always filtered trough a American propaganda lens, and they are never above just making stuff up if they can't find anything to take out of conext, they have always worked this way since at least the first world war.
