The capture of Crimea was not peaceful. I understand that you may not have investigated this issue. But where do you have evidence that Crimea was occupied peacefully?
What sources do you use to determine whether or not the occupation is peaceful? What is a peaceful occupation?
And what is war in this case?
I think it's all political concepts. Was there a war during the capture of Crimea or not. Wouldn't it be more logical to use an adapted organization for such definitions: the UN?

Politics inevitably intrude upon timekeeping, and this has been true for
millennia. The best we can do is minimize the effect; we cannot eliminate it.

As for timekeeping in conflict areas, we typically don't track it carefully. We
don't have entries for every town that changed hands during World War II, during
the wars in Congo since 1996, etc., etc. We and our users simply don't have the
resources for that. If a city already has an entry for other reasons we may try
to track its civil timekeeping through a conflict, but we won't create an entry
simply because there was a war and a city changed hands temporarily.

In short, tzdb is a peacetime database. It is not designed for conflict and
people engaged in a war will likely need to set their clocks by other means.
