It was an interesting question.  However, Zelensky’s response was so bad that FOX removed it from the video displayed later of the interview.   The Conservative Treehouse reported:

The question was asked during an interview between Brett Baier and Volodymyr Zelenskyy on Friday evening.  However, you will not find this segment on the rebroadcast of the interview at Fox News [Website Here] they took it out.  You will also not find this segment on the Fox News upload of the interview to their YouTube account [See Here] again, they took it out.

In fact, if someone had not uploaded a livestream copy to Rumble {Direct Link Here} there would be no other evidence the question was even asked, let alone the very flippant answer from Zelenskyy, “they are what they are“; where “they” is the neoNazi Azov battalion that have been merged with the Ukraine regular military.

Below is some information we published previously on the Azov Battilion.
