You realize of course that the Russian naval base in Sevastopol is older than than the United States, right ?

Not to pass judgement on the current Russian claim to Crimea, but it's a very short-sighted view to pretend that Crimea won't ever be Russian.

Yes, I have been in Sevastopol.

However, using blunt military force is not a way to present a territorial claim since 1945, among civilized countries. Especially after signing an agreement guaranteeing territorial integrity in exchange for nuclear weapons (Ukraine had produced and deployed most of Soviet ICBMs while it was a part of the USSR).

Whatever legitimacy Russia might have had over Sevastopol and Crimea, now lost forever. I, Russian citizen, can't go in Crimea anymore, because it amounts to visiting the occupied territory.

Some cite Israel of doing the same. Well, Israel gained Golan Heights / West Bank in response to all-out full destruction war against her (and is still being pressed quite hard by international community for it). Ukraine didn't attack Russia in any way.

The Russia that exists today is not the same Russia that existed when the naval base was built. It's a different country with the same name.

Well, it's a different government. I'm not sure it's a different country.

That's not the point. The point is many US companies can't sell products there whether it's "really" Russia or not.

Has any map provider, like Google Maps, changed Crimea to be part of Russia?

National Geographic, if you want to count them as a "map provider."

Google Maps is now displaying it as "disputed territory", like West Bank or Hans Island.

Depends on Country, actually. Google Maps displays it as "disputed" in most of the world, as "Ukraine" in the Ukraine, and as "Russia" in Russia.

The question is: what does Google displays in Crimea ?

The Internet providers assign Russian mainland IPs to Crimean users, to circumvent the sanctions regime, so they see it the same way Russia sees it.

I would hope that the message is 'Disputed Territory', however it probably depends on where the uplink is.

Sorry, anonymous poster, you can't deny objective reality.

If by "objective reality" you mean "Russia de-facto occupies Crimea with military force", then yes, it is undeniable.
