Russia is complying to the international security architecture formed after World War II, and will always counter attempts to undermine strategic stability, as well as attempts to replace the norms of international law with certain rules, including the UN Charter.
There are several well-documented cases of Russia violating international law, as well as ruining the international security architecture formed after World War II.
Over the course of the past decade, Russia has gone to war with Georgia; repeatedly interfered in the domestic political affairs of neighbouring countries; exerted various forms of economic pressure on states like Ukraine, Moldova, and Lithuania; and expanded its network of military bases in the post-Soviet region.
For example, according to international law, Crimea is part of Ukraine, and Russia violated international law, as well as the key principles of the European security framework, by illegally annexing the Autonomous Republic of Crimea and the City of Sevastopol.
On March 27th, 2014, the UN General Assembly adopted a resolution in which it stated that the referendum in Crimea was not valid and could not serve as a basis for any change in the status of the peninsula. Vladimir Putin, the President of Russia, recognised on April 17th, 2015 that "our soldiers were deployed in Crimea to help the inhabitants express their opinion".
Here are several disinformation cases on this issue.
