While yes modern weapons have higher yield, the point still generally holds the same. If you are in a heavy concrete structure, you actually have pretty decent odds. Now what access people have to that depends on where they live. From my experience on the east coast, a lot of the office buildings, etc in the DMV are mid 20th century brutalist concrete structures. So like even if you were in DC proper, your odds are surprisingly good as long as you are inside a building or in a metro station. My point wasn't so much that it's easy to survive. It's very much not. However it's not the guaranteed death a lot of people assume. Rather to quote, it's an earthquake, a tornado, and a wildfire all in one (plus radiation). If you are inside you lose the risk of radiation from the blast so now you just have to contend with the threat of 3 natural disasters at once. So if where you work is well suited for safety from a fire, from a tornado, and from an earthquake, you'll probably be in a reasonably safe space.
