In October, a jury convicted Ahmad Khan Rahimi, 29, of planting pressure-cooker bombs in NY and New Jersey on September 17, 2016.
Afghan-born Ahmad Khan Rahimi, 30, told the court that he became radicalized after being "harassed" by the Federal Bureau of Investigation and "singled out" for his religion, but showed no remorse for inflicting the bloody injuries.
The first explosion, on September 17, occurred along the route of a charity 5K race in Seaside Park, New Jersey.
Berman handed down the sentence in US District Court in Manhattan, ending the prosecution of Rahimi, who was convicted of the high-profile act of jihad-inspired terrorism that was widely considered a near miss, injuring dozens without killing anyone.
Rahimi is a naturalized US citizen who was born in Afghanistan.
He became a naturalized USA citizen in 2011.
Ahmad Khan Rahimi insisted "I don't harbor hate toward anyone" as he was locked up for blowing up a dumpster with a pressure cooker in New York City's Chelsea neighborhood. The other bomb, four blocks north, was discovered and rendered safe before it could explode.
While Rahimi wasn't charged for terrorism, his father, Mohammad Rahimi, had warned the Federal Bureau of Investigation in 2014 his son may have been radicalized.

Sweeney skidded out of the straight after the ninth turn and looped along the next curve, crashing into the wall with her feet. Germany's Natalie Geisenberger took home the gold medal once the competition resume, while American Erin Hamlin finished sixth.
"I've learned to understand why there's such frustration between the Muslim community overseas and the American people", Rahimi said, attributing this understanding to "life experience". Discs of the materials were found in two inmates' possession.
"You sound like most people and yet your actions are totally at odds with your voice", Berman said.
He was convicted of charges including the use and attempted use of a weapon of mass destruction, bombing a public place, destroying property by means of fire or explosives, and using a destructive device in furtherance of a crime of violence - namely, the use and attempted use of weapons of mass destruction.
Sajmir Alimehmeti was transferred away from Rahimi after being caught with materials from Rahimi's court case, including a USB stick with bomb-making instructions, New York Post reported.
Rahimi's attorney, Xavier Donaldson, said they plan to appeal.
Rahimi let other inmates view the items on his laptop and gave them electronic copies, Kim's letter said.
NYPD Commissioner James O'Neill praised the officers who responded to the Chelsea blast, as well as the authorities who tracked down and prosecuted Rahimi.
