United States President Joe Biden has delivered two different messages on the Israel-Hamas war to pro-Palestinian and pro-Israel Americans, NBC News has reported, based on copies of official White House correspondence.

While one letter showcased Biden’s support for Israel against Palestinian group Hamas’s “terrorism”, the other spoke about the US administration’s efforts to protect civilians in the Gaza Strip.

According to NBC, the letter sent to pro-Israelis invoked the Holocaust in relation to the October 7 Hamas attack on southern Israel. It also pledged continuous support to Israel and efforts to return the captives taken by Hamas and being held in Gaza.

“The people of Israel lived through a moment of pure evil” that “resurfaced horrible memories” and amounted to the “deadliest day for Jews since the Holocaust”, NBC reported Biden’s letter, dated November 1, as saying.

“The United States stands with Israel,” it continued. “We will continue to ensure that Israel has what it needs to defend itself against terrorism in accordance with international humanitarian law.”

On the other hand, Biden’s letter to pro-Palestinians focused on aid to Palestine and made no mention of the Holocaust or of US support for Israel.

“We mourn the many innocent Palestinians who have been killed,” NBC reported Biden’s second letter saying, dated November 8.

It added that the administration “is working closely with partners to ensure that life-saving assistance – including, food, water, and medicine can urgently reach innocent Palestinians in Gaza” and emphasised that “the United States stands unequivocally for the protection of civilians during conflict”.

While the two letters do not appear to contradict one another, or Biden’s policies, NBC reported that it was not common for the White House to craft different versions of a letter on the same topic that vary so much in their emphasis.
