No. Ukraine. Of which Crimea is a part.
And who reject the overthrow of the elected president of the Ukraine in a Western-backed revolution and are glad to be part of Russia again.
The elected president of Ukraine was overthrown by his own people in a revolution sparked by his refusal to sign an association agreement with the EU. The new government restored Ukraine's constitution to its status between 2004-2010, thereby preventing the corruption and authoritarianism that had allowed former president Yanukovych to exercise unreasonable power.
The Russian-sponsored Crimean independence referendum was unconstitutional under Ukrainian and Crimean law, and therefore illegal. It was also rigged; it did not provide the option to retain the status quo, so the only options were 'return to Russia' and 'return to the 1992 constitution' (which would facilitate a break into full independence from Ukraine). The option 'remain in Ukraine' was simply not offered.
The referendum was rife with irregularities:
* transparent ballot boxes
* ballots not placed in envelopes (so they were fully visible through the box walls)
* Ukrainian TV channels were made unavailable for Crimean residents, and some were replaced with Russian stations
*OSCE and UN observers were denied access, and attempts to enter Crimea for this purpose were met with violence
* the only observers permitted to oversee the referendum were those approved and backed by Russia
* only 34.2% of Crimea residents participated in the referendum
* many ballots had been pre-marked to support the pro-Russian option
* Russian citizens were allowed to vote
I could go on and on.
