There are Russian, North Korean, and Iranian troops fighting in Ukraine
There’s conflict in the Middle East between Israel and Palestine
China is playing a game of brinkmanship with Taiwan and The Philippines.
If things heat up, future historians may place the beginning of world war 3 on the Russian invasion of Ukraine.
