World Cup 2022: Which Middle East leaders were at the opening ceremony?
That same message may have resonated for the dignitaries who turned up - with several leaders of countries, some of whom have been hostile to each other in recent years, pictured smiling and embracing.
Chief among them was Turkish President Recep Tayyip Erdogan and his Egyptian counterpart Abdel Fattah el-Sisi, who met and shook hands for the first time at the ceremony on the sidelines of al-Bayt Stadium in al-Khor, on the outskirts of Doha.
Relations between Ankara and Cairo have been fractured for nearly a decade. Turkey refused to recognise Sisi as Egypt's legitimate leader following a 2013 military coup that ousted his predecessor Mohamed Morsi, the country's first democratically elected president.
Saudi Arabia Crown Prince Mohammed bin Salman was filmed speaking at length with Algerian President Abdelmadjid Tebboune, just weeks after he skipped the Arab League summit in the North African country citing health concerns.
The de-facto Saudi leader wore a Qatar football scarf, clapping and listening intently as Qatari Emir Tamim bin Hamad Al Thani opened the tournament with a speech in Arabic.
Five years ago, the crown prince led an economic and political blockade of Doha, accusing it of meddling in internal affairs and supporting terrorism, charges that Doha denied vehemently.
Other leaders from the region in attendance included King Abdullah II of Jordan, Palestinian President Mahmoud Abbas, Lebanon’s caretaker Prime Minister Najib Mikati and Dubai ruler Mohammed bin Rashid Al Maktoum.
The leaders, as well as over 60,000 fans, enjoyed performances from Qatari singers Dana and Fahad al-Kubaisi, as well as Jung Kook, a member of South Korean boyband BTS.
American actor Morgan Freeman also delivered a message of unity and overcoming divisions with disabled Qatari influencer Ghanim al-Muftah.
Hosts Qatar were comfortably beaten by Ecuador 2-0, thanks to two first-half goals by former West Ham and Everton forward Enner Valencia. Many seats remained empty after half time, and a flat second half prompted further walkouts before full time.
