Prosecuting, the US government said the case showed its determination after 9/11 to prevent terrorist attacks in the planning stages.
At the time of their arrest, officials said that an attack had been imminent.
But during the trial prosecutors said the groups was probably months away from any attack and did not necessarily have a specific plan.
The government relied heavily on information provided by two FBI informants who infiltrated the group of men and secretly recorded hundreds of conversations involving the suspects.
Prosecutors also said men bought rifles from the FBI and went to the Pocono Mountains in Pennsylvania to practise using them.
But defence lawyers said any talk of militancy was only bravado.
(Some daydreamers were spotted as good patsies for the FBI to use to show they are catching "terrorists". As usual, these people could not have carried out any part of their wet dreams without the help of the FBI. Just like the Miami 7 who were taught how to make bombs by the FBI to blow up the Sears Tower. The FBI can't find real terrorists so they create them to show they are doing their job. - CHIMP)
