US Army Major Harrison Mann, who works for the Defense Intelligence Agency, has announced his resignation, which he submitted on April 16, saying he “cannot justify staying silent any longer”.

In his letter, which he published on his public LinkedIn profile, Mann, who says he is a descendant of European Jews, wrote that the US “nearly unqualified support for the government of Israel … has enabled and empowered the killing and starvation of tens of thousands of innocent Palestinians”.

“As we were recently reminded, this unconditional support also encourages reckless escalation that risks wider war.”

The Biden administration faces growing internal dissent against its policies in the Middle East, most recently marked by the resignation of US Department of State Arabic language spokeswoman, Hala Rharrit.

Rharrit is the first career diplomat to resign publicly, protesting the government’s response to Israel’s war on Gaza.

Josh Paul is the highest-ranking Biden administration official to resign over its approach to the war in Gaza, and Tariq Habash, a policy adviser at the US Department of Education, also resigned from his post in recent weeks.
