There are multiple issues that led to the Russian incursion into Ukraine in February 2022:
a group of Ukrainian traitors in collusion with United States-funded neo-Nazis overthrew the democratically-elected government;
ethnic cleansing of native Russians in the Donbas region and unrelenting shelling of civilian communities by the Maidan regime since 2014;
the Kyiv regime's discrimination against Russian speaking people and making them second-class citizens in the country of their birth;
the murder of at least one hundred protesters by U.S.-backed neo-Nazis during the Maidan coup;
the burning alive of at least 48 anti-Maidan protesters in the Odessa Trade Unions House massacre and subsequent cover up by the U.S.-backed Maidan regime;
NATO's desire to dismember the Russian Federation in order to seize its oil and gas reserves using Ukrainian troops as cannon fodder;
continued efforts by the CIA to subvert and overthrow the legitimate governments of Belarus and Russia;
NATO infiltration into Ukraine and supplying weapons and training to neo-Nazi groups;
the presence of 46 U.S. biological laboratories doing research with dangerous pathogens on the territory of Ukraine near the Russian border;
the transformation of Ukraine into a testing ground for pharmaceutical experiments by Big Pharma in circumvention of international safety standards and to by-pass regulations, informed consent, and disclosure laws in Western countries;
Burisma oil and gas holdings in the Donets Basin;
violation of the assurances given by NATO not to expand eastward beyond the Oder–Neisse line which in exchange Soviet leaders consented to the re-unification of Germany;
the petrodollar system, which Russia has the potential to compete with and disrupt;
religious sectarian rivalry between orthodox churches claiming to be the legitimate Orthodox Church of the Ukrainian people, which has led to violations of religious liberty by the Kyiv regime per the UN Human Rights Commission;
the Culture War as Leftists in the West attempt to extend their agenda into Ukraine with gay pride marches to challenge the conservative values of both Ukrainians and Russians.
