Being born in 1967, WWIII seemed potentially imminent for the first 20 years of my life. There's wasn't particularly a solution, you just go on anyway.

If you're the leader of Russia, you have a good way of preventing this. If you're not, it's out of your control, so just focus on the things you can control.

This is absolutely true, and also why this can cause so much anxiety in most people. More people are afraid of flying in airplanes than driving a car precisely because they have no control over the outcome. Posting an opinion on social media about Ukraine, despite having less impact on the situation than a pebble dropped in a lake, can make some feel better. That might not be a bad or useless thing.
