Their crimes could have brought devastation and carnage to the streets of Yorkshire.
Here we take a look at the evil terrorists now behind bars thanks to counter terrorism police across Yorkshire.
Not only did Wayne Bell, 37, post an image on a Russian social media site showing a man being hung by a rope with a Star of David on his forehead, but he also described Jewish people as "destructive and vile".
Bell, of Mount Walk, Castleford, was also behind hate-filled graffiti.
13 videos were found on Bell's mobile phone and featured an unseen man - believed to be Bell - directing others who were daubing anti-Semitic graffiti, including swastikas and references to the Holocaust.
He was jailed for four years and three months.
Jack Coulson, 19, made a pipe bomb in his Nazi memorabilia-filled bedroom.
Coulson, of Mexborough, also downloaded The Big Book of Mischief to his phone after allegedly boasting about wanting to kill a female MP following MP Jo Cox's death.
He was sentenced to four years and eight months.
