In four years, Donald Trump overturned decades of U.S. policy in the Middle East.
But how much of that is likely to survive now that there’s a new president in the White House?
Joe Biden is likely to want to undo many of Trump’s changes - but his freedom for manoeuvre will be limited.
Biden's choice for secretary of state, Antony Blinken, has signalled that countering Iran would be key.
"When it comes to Iran, a couple of things: First, President-elect Biden is committed to the proposition that Iran will not acquire a nuclear weapon.”
But he also admitted the U.S is “a long way” from rejoining the 2015 Iran nuclear deal - designed to restrain Tehran’s nuclear programme.
Trump Heights, Trump Square, Trump train terminal...the former U.S. president certainly left his stamp on Israel, where he is widely admired for his staunch support of the country.
His administration recognized Jerusalem as the capital of Israel and accepted the Israeli sovereignty over the Golan Heights.
But in the Palestinian territories, no U.S. president was so openly reviled.
At his Senate confirmation, Blinken signalled the Biden administration would return to pre-Trump, diplomatic norms.
"... the only way to ensure Israel's future as a Jewish democratic state and to give the Palestinians the state to which they are entitled is through the so-called two-state solution.”
Biden has vowed to restore Palestinian ties cut by Trump through resuming aid and pushing back on Israeli settlement expansion.
But Trump legacies are likely to remain - like the U.S. embassy’s location in Jerusalem.
Eitan Gilboa is an Israeli political science expert and says Trump’s most important achievement were normalization agreements signed between Israel and the UAE, Bahrain, Sudan and Morocco.
“These agreements have changed the international and regional landscape of the Middle East because for the first time in years, an opportunity emerged for a comprehensive Arab-Israeli peace ... Prime Minister Netanyahu and Trump have established very close and intimate relationship. This represent an aberration in Israeli American relations that will not continue with the Biden administration.
The diplomatic deals are likely to remain as they have bipartisan support in Washington, and brought a strategic realignment of Middle East countries against Iran.
