I once spent a month in Ukraine teaching English at a summer camp. Every morning we sang the marvelously defiant Ukrainian national anthem Shche ne vmerla Ukraina. I still know it by heart. Knowing the lyrics makes the following scene reported by the Guardian even more amazing:
The naval head, Denis Berezovsky, who on Sunday announced he was defecting to the Russian-backed Crimean authorities, addressed officers at naval command in Sevastopol to try to convince them to follow suit. But his replacement, Serhiy Haiduk, was also present and appeared to win the day. The officers broke into applause as Haiduk read them an order from Kiev removing Berezovsky from his position, and told them that Berezovsky was facing treason charges. When Haiduk had finished his dry but compelling address, the officers spontaneously broke into the national anthem, and some were seen to cry. Berezovsky showed no visible sign of emotion.
Here is the anthem in full:
