I hate to be that guy, because i dislike modern Ukraine. But the trident is a very old Slavic symbol that originates with king Volodymr of the Kievan Rus. The Kievan Rus are the ones that removed the Khazars from Southern Ukraine in the first place, as another commenter has noted.
Similar symbols have been found on khazar tamgas, but the symbol as it concerns Ukraine is of the Rurik dynasty and the Kievan Rus. The first use of the *modern* symbol was the Ukrainian people's Republic, an anti Bolshevik vassal of the Russian Republic.
It's a coincidence. It's a symbol unrelated to Jews that belongs to an ethnically non-jewish country which Jews have taken control of. A lá the eagle of the United States
It's not really a coincidence. I compiled evidence on Scored that Prince Vladimir adopted the trident on his coins *because* he had conquered the Khazars who used it; his father's tamga was markedly different. However, those who credit the Khazars with converting to Judaism must also credit Kievan Rus with converting to Orthodox Christianity about 988, so the trident tamga thus becomes a symbol adopted by Christians.
In its modern incarnation it draws on many different traditions including these two. Therefore even with the Jewish conversion there are many strands of symbolic input, not just Jewish.
