(FILES) (COMBO) This combination of pictures created on November 07, 2024 shows US President Joe Biden meets with Israeli Prime Minister Benjamin Netanyahu (L) in the Oval Office of the White House in Washington, DC, on July 25, 2024, and former US President and Republican presidential candidate Donald Trump (R) arrives to speak during a campaign rally at the J.S. Dorton Arena in Raleigh, North Carolina, on November 4, 2024. Donald Trump has not yet returned to the White House but is already thrusting himself to the front of international stage as he once again shatters diplomatic niceties. As only the second former president elected to a non-consecutive term, Trump is at least a known quantity to world leaders. Even his knack for unpredictable behavior is predictable.
