I don’t think he is. I think he is straight out saying what he thinks. There are a lot of vets who fall on different sides of a Uke/Russian conflict.
Being American simply doesn’t require one to support either side.
In fact, the whole democrat party, the Biden crime family, the Clintons, Obama, the EU, the globalist McConnell type repubs, all of the mainstream media, CNN, MSNBC, the NYT, Facebook, the WEF, Hollywood, Sean Penn, the LGBT crowd .... you name it, every woke diabolical attacker of American culture is on the Uke side.
They didn’t all suddenly become patriots.
He starts this interview with the Markale massacres (without clearly naming it, a classic shill's trick) where mortars hit the marketplace, and claims we now know it was a false flag by Bosniaks. All the evidence pointed to Bosnian Serb. There is no evidence that it was done by the Bosniaks at all.
Anyone who starts off a interview that fluid with facts and history is going to keep being fluid with facts and history for the rest of it.
