This isn’t an attack _yet_. This is potentially a part of the process of developing the capabilities for a later attack.
Crimea is the first time a nation state has meaningfully changed its borders that I know of since WW2. As a result I would consider Crimea a much more egregious attack on American values and western interests than a software vulnerability that hasn’t been leveraged to cause actual harm.

I took a look out of curiosity, and there have been a lot more border changes in the world than I was expecting. Lots due to decolonization in Africa. The partition of India in 1947 was huge. Lots of European changes, of course. Many small border cleanups. The changes go on for page.
