Bout was convicted of conspiracy to kill US citizens and officials, deliver anti-aircraft missiles and provide aid to a terrorist organisation.
"Viktor Bout was ready to sell a weapons arsenal that would be the envy of some small countries."
In the opening statements of his trial the prosecution alleged that Bout had agreed to deliver 100 surface-to-air missiles, 20,000 high-powered rifles and 10m rounds of ammunition to rebels in Colombia in 2008. They told the jury that Bout had been told the weapons would be used to target US pilots working with Colombian officials.
Prosecutors say Bout replied: "We have the same enemy."
That doesn't mean you didn't break the law, Vik...
But the defence argued Bout was just trying to sell two old cargo aircraft for $5m (£3.1m). "Viktor was baiting them along with the promise of arms, hoping just to sell his planes," lawyer Albert Dayan told the court.
He will be sentenced on 8 February 2012 and could face a maximum term of life in prison.
