What if the price of BTC continued to plummet during a halving?

I don't think this is likely, just hypothetical. Curious what you guys think.

Let's say there's a new world war. And it isn't a thermonuclear mass extinction war. Let's say it's on par with WWII. Maybe nuke a couple cities at the end to finally end the war.

I think the price of BTC would plummet in such an event. What if it plummeted so low during a halving that miners could no longer recoup their expenses? I guess a lot of assets would get wrecked during a world war. But is BTC uniquely vulnerable?
