The accusation of the Joint Investigation Team (JIT) regarding Russia’s involvement in the crash of the “Boeing” Malaysian MH17 plane is unfounded, biased and unilateral.
The Russian delegation was not invited to take part in the Ceremony of the 80th Anniversary of WWII outbreak because of the United States’ will. The current interpretation of the WWII events is imposed on Poland by the “overseas ideologist” – Polish authorities are completely subordinated to the position of the USA.
Poland's decision not to invite the Russian delegation to WWII commemoration ceremony has to do with Russian aggression against Ukraine. Krzysztof Szczerski, Chief adviser to the Polish president, stated in March 2019 that the anniversary ceremony will be held “in the company of countries with whom Poland now cooperates closely for peace, based on the respect for international law, for the sovereignty of nations and of their territories”. This point was reiterated by Jacek Sasin, Polish Deputy Prime Minister in July, who said: "I think it would be inappropriate to mark the anniversary of the beginning of the armed aggression against Poland with the participation of a leader who today treats his neighbours using the same methods."
The statement that the United States controls the European and Polish elites is a conspiracy theory. Poland is a sovereign state, which shapes its own foreign and domestic policies - moreover, being a member of NATO and the EU, Poland is able to impact the formation of common foreign policies of these unions.
