Osama bin Laden’s son has vowed to seek revenge on America for killing his father — a threat that could be propaganda to boost al Qaeda’s sagging recruitment after the rise of ISIS, experts said.

“We will continue striking you and targeting you in your country and abroad in response to your oppression of the people of Palestine, Afghanistan, Syria, Iraq, Yemen, Somalia and the rest of the Muslim lands that did not survive your oppression,” Hamza bin Laden declared in an audio recording, the SITE Intelligence Group said Sunday.

“As for the revenge by the Islamic nation for Sheik Osama, may Allah have mercy on him, it is not revenge for Osama the person, but it is revenge for those who defended Islam,” Hamza, 23, said in the speech titled, “We Are All Osama.”

His threats may pack little punch at a time when al Qaeda’s influence is waning as it loses territory and fighters to ISIS.

But a youthful poster boy like Hamza could help revitalize the terrorist group, experts warn.

“Hamza provides a new face for al Qaeda, one that directly connects to the group’s founder. He is an articulate and dangerous enemy,” said Bruce Riedel of Brookings Institution, one of Washington’s oldest think tanks.

Hamza bin Laden was with his father in Afghanistan before the 9/11 attacks and spent time with him in Pakistan, according to the Brookings Institution.

Later, he was held under house arrest in Iran while his father hid out in Pakistan, according to documents recovered from Osama bin Laden’s compound.

Osama was killed by US commandos at his hideout in 2011 — a major blow to the terrorist group.

Hamza, whose whereabouts are unknown, was given explosives training. He reportedly wrote his father requesting to be part of the battle against the US.

He is Osama bin Laden’s youngest son. His brother Khalid was killed in the 2011 raid.

On social media, Hamza was met with skepticism.

“Good luck traveling to the US if your name happens to be Hamza,” joked Pakistani TV editor Omar Quraishi.

And when it was reported that Hamza was poised to take over al Qaeda last May, Twitter user Stephan Proctor wondered, “Who knew who Hamza Bin-Laden was before this article?”
