Looks nobody noticed yet, or didn't pay attention.
Do you remember the file with Bogdan Khmelnitsky letters Putin gave Tucker?
Now think - why is it so thick and heavy? Copies of all Khmelnitsky correspondence could not be so thick and heavy.
What else was in that file?
I didn't heard anything I didn't already know in this interview, but things like above was interesting to see and notice.
Also, f.e. it was clear that Tucker was completely unprepared for such intellectual discussion. Putin didn't fit into his way of interviewing. It's funny that such manner of telling stories is very common in Russia, like "wait, I just started, let me tell the whole story, I'll eventually come to the topic". It is perfectly fine here, especially in long winter evening with some vodka, pickles and stove cooked dishes, when two or more people have a long and thoughtful conversation, but looks like it is completely alien to Tucker itself and his audience in general. Some cultural differences, many omit from equation.
