There are two versions of the events [regarding the German Ministry of Foreign Affairs summoning the Russian ambassador in relation to the cyber attacks on Bundestag in 2015]. Either they have a trump card, for example a photo of S.Naryshkin [the director of Russian Foreign Intelligence Service] awarding a hacker for the attack, or the Germans really want the Nord Stream 2 pipeline, against the wishes of the other Europeans and Americans. The Germans are facing an enormous pressure and must make some kind of reverences. And the reverences to Americans are always Russia-related. […] And then there is a second reason, and I might be mistaken but I suspect it exists: the Russian envoy to Germany was summoned the next day after it was announced that Russia will hold a Victory day parade on the 24th of June. Earlier, it was discussed in Germany that it would be represented at a very high level, possibly the Chancellor, and now they have a pretext not to come.
The Crimean peninsula became part of Russia after the events of 2014 in Ukraine, when power changed in the country as a result of a coup. The decision was made following the results of a nationwide referendum, in which more than 80% of Crimeans participated. More than 95% of Crimean residents voted for reunion with Russia. Despite the results of the referendum, Kyiv denies the peninsula’s right to self-determination and refuses to recognise it as part of Russia.
Recurring pro-Kremlin disinformation narrative about the annexation of Crimea, claiming that Crimea voted to rejoin Russia through a legal referendum. Crimea is a part of Ukraine and was illegally annexed by Russia. In 2014, Russian troops obliged the parliament of Crimea to organise a referendum, which was illegitimate under international law, and then formally annexed the peninsula and brought it under Russian territorial control. The annexation has been condemned by the UNGA (see the resolution A/RES/68/262 on the territorial integrity of Ukraine). No international body recognises the so-called referendum, announced on 27 February 2014 and held on 16 March 2014. Following the covert invasion by “little green men,” the referendum in Crimea was conducted hastily and at gunpoint, barring impartial observers from entering the peninsula. A year after the illegal annexation, Russian President Vladimir Putin admitted that the plan to annex Crimea was ordered weeks before the so-called referendum. The European Union does not recognise Crimea's annexation and continues to condemn it as a violation of international law. EU sanctions continue to be in place against Russia as a consequence of the annexation. For the EU's statement on the sixth anniversary of Crimea annexation see here. The article also claims that sanctions against Russia are not effective, and some countries are urging the EU to weaken or lift the sanctions against Russia. See the case: EU is suffering from sanctions against Russia. It also said that restrictions do not have any effect on Russia, whose economy has long adapted to them.
