Her first draft was harsher on Israel, sources previously told NBC News, although a spokesman for Ms Harris denied these reports.

Officials who quit the Biden administration to protest against the White House response to the war in Gaza have said they are “cautiously optimistic” that Ms Harris would be willing to consider policy changes to protect Palestinians.

Josh Paul, a former State Department official involved with transferring arms to American allies, told Politico Ms Harris seemed less “fixed and intransigent” than Mr Biden on the issue.

Such an approach could help regain Democrat voters put off by Mr Biden’s response to the war in Gaza.

Ms Harris is a supporter of the two-state solution. Asked whether it was “achievable” at the Munich Security Conference this year, Ms Harris said: “The short answer is yes.”

Ukraine

Ms Harris is staunchly in favour of helping Ukraine defend itself against Russia.

She has met Volodymyr Zelensky six times and has appeared on the world stage in Mr Biden’s place at key gatherings on the war.

At the Summit for Peace in Ukraine in June she pledged her “unwavering commitment” and in each of her three addresses to the Munich Security Conference she said the US was committed to helping Kyiv defend itself.

She has said the US will support Ukraine for “as long as it takes” and warned that a failure to supply weapons and resources to Ukraine would be a “gift” to Vladimir Putin.

This year she appeared to take a swipe at Trump and Republicans as she attacked people in the US who want to “isolate” the country, “embrace dictators” and “abandon commitments to our allies”.

“Let me be clear: That worldview is dangerous, destabilising, and indeed short-sighted,” she said.

Ms Harris attacked Trump during the election campaign for his claim that he would pull the US out of Nato.

“Donald Trump has embraced Putin,” she said at a North Carolina campaign event earlier this year.

She added: “It’s not just happening today. It’s been happening, as he, Trump, threatened to abandon Nato and encouraged Putin to invade our allies.”
