reject any plan that returns Crimea to Ukraine even it allows a referendum in Ukraine to decide if Crimea can be leased to Russia for 50- 100 years. Anyone if they are serious to follow Russia/Ukraine/Crimea situation therefore understand the reality should know Russia and Putin's stand on Crimea. Crimea was part of Russia since 1780 and is part of Russia now. It belonged to Ukraine only during 1954 - 2014. By no means Russia will return Crimea to Ukraine. If any serious journalists understand Russia's stand and reality, they should suspect the claim that the plan received encouragement from Putin.
P.S. Russia is building Crimea bridge which connects Crimea and Russia. The project ate up half budget of Russia's total transportation spending of 2016. It will be finished by the end of this year (construction speed is amazing). By then Crimea will be physically connected to Russia.
