How would this be proven? Hard to take fingerprints on the site. We would have likely used a Special Forces or SEAL team and submersibles that could avoid sonar detection. If we did it, the Russians have probably already scoured all available satellite data, flight records, etc, and came up empty.

How would it be proven?
Any public statement made by any head of state and/or any of his underlings, say, two of them, would be a very strong fact in evidence to that effect, frankly.
“How would this be proven?”
Perhaps if the US president pre-confessed to it.
You’re probably right nobody can ever prove beyond all doubt who did this. Although you don’t need a satellite to see US Navy was exactly in that spot that week. They announced it in social media.
No, we would have used Ukrainians.
