[11] In the majority of his motions, he opposed the introduction of the Russian language as the second official state language; proposed recognition of the fighting role of the Organization of Ukrainian Nationalists and the Ukrainian Insurgent Army during World War II; called for the lustration (regulation of political involvement) of former communist officials, security-service officers and undercover agents; and demanded the prohibition of communist ideology.

[11] On 20 July 2004 Tyahnybok was expelled from the Our Ukraine parliamentary faction[9][12] after he made a speech in the Carpathian Mountains at the gravesite of a commander of the Ukrainian Insurgent Army.

They took their automatic guns on their necks and went into the woods, and fought against the Muscovites, Germans, Jews and other scum who wanted to take away our Ukrainian state.

[14][15] The prosecutor's office initially filed criminal charges for inciting ethnic hatred, but later withdrew them for lack of evidence.

Court decisions have recognized that the criminal case was raised unlawfully, and that the actions of TV-channel "Inter" (which showed the footage of Tyanybok's speech) as well as of the Head of the Derzhkomnatsmihratsia Hennadiy Moskal were recognized as ones that insult the honor and dignity of Oleh Tyahnybok and caused him moral damage.

[6] A year after his speech, Tyahnybok wrote an open letter to President Viktor Yushchenko demanding that he "put an end to the criminal activities of Ukrainian Jewry".

[11][18] Tyahnybok stood as a candidate for President of Ukraine in the 2010 presidential election representing the All-Ukrainian Union "Freedom" party.

[26] In June 2013, Tyahnybok and another Svoboda leader were barred from entering the U.S. for their open antisemitism, according to the Kyiv-based newspaper Segodnya.

[28][29] In March 2014 Russia launched a criminal case against Tyahnybok, and some members of Ukrainian National Assembly – Ukrainian National Self Defence for "organizing an armed gang" that had allegedly fought against the Russian 76th Guards Air Assault Division in the First Chechen War.

[34] On 14 October 2018, Tyahnybok announced he would not take part in the 2019 Ukrainian presidential election but that his party had instead decided to nominate Ruslan Koshulynskyi as the candidate of nationalist political forces.

[36] In the 2019 Ukrainian parliamentary election Tyahnybok was placed first on the joined list of Svoboda with National Corps, the Governmental Initiative of Yarosh and Right Sector.

[38] Unlike both imperialism and globalism, modern nationalism seeks a healthy balance between domestic development and productive international relations.

[39][6][40] In 2012 international human rights organization The Simon Wiesenthal Center placed Tyahnybok fifth in its list of the top 10 antisemites and haters of Israel, based on his previous comments regarding Jews in Ukraine.

[13] He has accused the Medvedev presidency of "waging virtual war on Ukraine along many fronts – in the information sphere and the diplomatic sector, within the energy trade and throughout the world of international PR spin.
