Yes you're right - misinterprering by responding to part of a thread is rude.

Which is what you're doing - because the context of the thread is more specifically that anyone foresaw it - 'He couldn’t foresee that. No one did.' and the person I'm replied to that saying that they thought just some like Taiwan foresaw it.

Both are demonstrably false claims - you can look at public national security risk registers to confirm to yourself that many other countries foresaw it.
