As I sat there, absorbing the touching messages that had been delivered during that ceremony by President Reuven Rivlin and IDF Chief of Staff Lt.-Gen. Aviv Kohavi, my phone rang.
It was US President Joe Biden.
An aide to the president with whom I’ve had contact in the past made the call, but after just the briefest of pleasantries, he said: “Hold on.”
And then I found myself on the phone with the president.
"I'll make this brief. No substance. I know this is a sacred night in Israel,” said Biden.
“My aides have told me about you. I remember that many years ago, you interviewed me on [Remembrance Day] and then played the interview on your radio station on Independence Day."
He was referring to my days working at the Israel Broadcasting Authority, when I did extensive diplomatic and political reporting for the English-language service of the IBA’s Kol Yisrael radio network.
The previous conversation with Biden had been back in the days when he was on the Senate Foreign Relations Committee, including a period when he served as chairman of the committee.
I had been trying for some time to arrange that interview; when I offered to conduct the conversation with him to mark the occasion of Israel’s Independence Day, he accepted the invitation.
The aide through whom I had arranged that radio interview long ago no longer works for Biden. The current contact was formed with the assistance of a former White House aide to Barack Obama, with whom I became connected in 2009 through a senior US Jewish figure.
During the two terms of the Obama presidency, the presidential aide and I would speak periodically about Israeli life and issues relating to Israel and the American Jewish community. The conversations were informal and generally not for direct attribution in my news reports.
However, in the final months of Obama's second term, I was given the opportunity to chat with the president directly over the phone on two occasions.
Still, it was a total surprise when years later, I picked up the phone to hear the White House on the other end of the line.
"Thank you for all you do; you show people the beautiful side of Israel," Biden said to me in Tuesday's conversation.
I thanked him, the conversation ended, and I went back to observing Remembrance Day after talking to the president of the United States.
