* At the 2014 opening ceremony, in protest of the Crimean crisis, Ukraine sent out only its flagbearer during the Parade of Nations. Simple, yet powerful.
* The volunteer who walked out with the Afghan flag by himself during the Tokyo 2020 Parade of Nations. Afghanistan had just fallen to the Taliban again, and the organisers weren't sure if their athletes would be even be able to get out of the country to compete, but decided to parade the flag as a signal of hope. Thankfully, the two Afghan athletes had managed to leave, and took part in the games, arriving a few days later than planned.
