US and North Korea: Trump-Kim (2018)
US President Donald Trumpâ€™s handshake with North Korean leader Kim Jong-un in Singapore on Tuesday marked a historic moment — the first meeting ever between a sitting US president and the leader of North Korea.
The extraordinary encounter saw the leader of the worldâ€™s most powerful democracy shake hands with the third-generation scion of a dynastic dictatorship, standing as equals in front of their nationsâ€™ flags.
South and North Korea: Moon-Kim (2018)
On April 27, 2018, as the world held its breath, Kim Jong-un and South Korean President Moon Jae-in reached across the Military Demarcation Line that divides the two Koreas and shook hands, the result of a remarkable thaw on the peninsula sparked by the Winter Olympics earlier in the year.
Kim then stepped over the border for a summit with the South Korean president, making him the first leader from Pyongyang to set foot in the South since the Korean War ended in an armistice 65 years ago.
The two leaders agreed to pursue permanent peace and the complete denuclearization of the divided Korean Peninsula.
US and Cuba: Obama-Castro (2013)
At a memorial service for Nelson Mandela on Dec. 10, 2013, US President Barack Obama made headlines when he shook hands with Cubaâ€™s Raul Castro, the first such public greeting between leaders of the bitter neighbors after decades of enmity.
Within months there was a rapid thaw. Full diplomatic relations were restored in July 2015, followed by once-unthinkable steps to mend ties.
Obama visited Cuba in 2016 — the first such trip by an American president in 88 years.
Northern Ireland: Elizabeth II-McGuinness (2012)
In a landmark moment in the Northern Ireland peace process, Britainâ€™s Queen Elizabeth II met Martin McGuinness, a former top commander in the paramilitary Irish Republican Army during the many years of bloody hostilities with British forces.
The IRA wanted an end to British rule in the province, and for it to be merged with the Republic of Ireland. McGuinness later became one of the figures that helped negotiate an end to the violence.
Then a deputy first minister of Northern Ireland, McGuinness shook hands with the queen during her June 27, 2012 visit to the province.
It was a gesture toward reconciliation that would once have been unimaginable, with McGuinnessâ€™ militant past and British security operations still a source of anger for many.
Israel and Palestinians: Arafat-Rabin (1993)
After months of secret negotiations in Norway, Israeli Prime Minister Yitzhak Rabin and Palestinian leader Yasser Arafat stood in the South Lawn of the White House on Sept. 13, 1993 to witness the signing of the Oslo Accords.
And then, in one of the most dramatic moments in the Israeli-Palestinian conflict, with US President Bill Clintonâ€™s arms stretched around both leaders, Arafat and Rabin shook hands.
The abortive process granted autonomy to the occupied Palestinian territories without creating a separate state.
Rabin was assassinated two years later by a Jewish extremist opposed to the peace process, which faltered in the years that followed.
Egypt, Israel: Sadat-Begin (1977)
In what is widely considered a major turning point in the recent history of the Middle East, Egyptian President Anwar Sadat arrived in Israel on Nov. 19, 1977 on a historic visit — the first by an Arab head of state to the Jewish nation.
Images of Sadat shaking hands with Israeli Prime Minister Menachem Begin during the visit were transmitted around the world. The visit led to the first Arab-Israel peace treaty and the formal end to the state of war that had existed between the two countries for 30 years.
Sadat paid for it with his life: He was assassinated by Islamists in 1981.
