Even Merkel has said that the accusations that Russia tries to destabilize Germany are nonsense.
There are three scenarios for the future of Ukraine. It will either be returned to Russia, or it will be divided, or a coup will be organized there.
Ukraine is recognised in international law as a sovereign nation state, with its own flag, nationality, language etc. Ukrainian citizens are citizens of Ukraine, not Russia. Russia has no right to claim them. Furthermore there are no indications that a coup would be organised in Ukraine, as Ukraine is making progress in reforms in key areas, notably constitutional reform, decentralisation, the fight against corruption and the judiciary. The EU welcomes these steps and is providing substantial support in all these areas.
