The US leadership is carrying out active diplomatic, economic (including sanction pressure) and propaganda campaigns against Russia. The US-NATO military build-up is ongoing along Russian borders in Eastern and Northern Europe. The US and its allies are openly backing the so-called ‘non-system opposition’ in Russia (the part of the opposition that openly aims to overthrow the government by non-constitutional means and destroy the Russian statehood). This ‘opposition’ includes various radicals and destructive forces that employ methods and tools that have been already demonstrated in Ukraine in 2013-14.
A conspiracy theory, presented without any evidence. The article is in line with a narrative that protests, in this case in Russia, are always financed by outside forces. The protests in Moscow started in July after the election committee banned opposition candidates from running for the elections to the city council - the Moscow City Duma, disqualifying their ballots because of what officials claimed were irregularities in the 5,000 signatures each had to gather to run. The protesters also demanded the right to fair elections and the right to free assembly - all along the lines of the Russian constitution.
