"For the past ten years, the US authorities have been directly and through the media waging war against me and my family," Mr Bout said in a recent interview with the Russian news agency RIA Novosti.
"We have been buried under a torrent of lies," he said.
Mr Bout's brother Sergei, who's accused of being an integral part of the business, is currently living in Moscow and agreed to be interviewed at a restaurant in an upmarket shopping centre.
Sipping green tea during the interview, he also dismissed the allegations against them.
But he quickly shifted from charm to aggression when pressed about evidence gathered by a United Nations investigator called Johan Peleman.
"I know Mr Peleman… yes very nice investigator," he said.
"They came to Dubai to a five-star hotel, very nice, beautiful hotel and sat there and investigated… is that an investigation?
"He is a diamond expert, he does not know about ammunitions," he added.
The big question now hanging over the trial in New York is whether much more will be revealed than what Viktor Bout is alleged to have said during the sting operation in Bangkok.
For Russia it could be extremely embarrassing.
But it could be equally embarrassing for the United States and other Western countries, which are also alleged to have taken advantage of Mr Bout's services to fight their wars in different parts of the world. bbc
