Theres a really good documentary that concerns this called 'Revealing Ukraine' by Oliver Stone that everyone should check out

2014: Leaked phone call between Asst. Sec. of State of Europe Victoria Nuland and US ambassador to Ukraine Geoffrey Pyatt discuss a coup operation in Ukraine. Specifically mentions VP Biden

In 2012, Burisma holdings was being investigated for money laundering. Owner of the company Mykola Zlochevsky was good friends with ousted president Viktor Yanukovych (a guy with close ties to Putin) and he made Mykola Sec. of Defense. Mukola then gave Burisma a bunch of very good government contracts too which was also being investigated. Then Hunter Biden joins Burisma in 2014, and soon after, the infamous case of Biden getting the prosecutor in the Burisma case fired happened.

2016: A seemingly low level DNC operative, Alexandra Chalupa, is named one of the most important people of the 2016 election. Why? Her spearheading an investigation into Paul Manafort

While this is happening during the 2016 election, the US embassy in Ukraine intervenes in their continuing corruption investigation. Specifically telling them NOT to investigate 'The Anti-Corruption Action Center'. A group founded by Barack Obama and had massive donations from none other than George Soros. This group was also working with the FBI in the Paul Manafort investigation. Hmmmm

May 2016: Wikileaks publishes email exchange between DNC comms director Luis Miranda and Alexandra Chalupa. In it, she brags about using Soros backed groups like the 'Open World Society' to work with Ukrainian journalist to dig up dirt on the Trump campaign

Then in 2019, the Ukranian government reveals that Chalupa made contact with them and tried to get them to work with the DNC to dig up dirt on Trumps campaign too. They refused bc this would clearly be interfering with the US election by a foreign state. Chalupa, who is of Ukranian decent, was decietful with who she was too. She made it seem like she was just some independent activist and not a hatchetman of the democrats.

All of this make THIS article from 2017 much clearer. The Biden-DNC-Ukraine issue is really fucking deep, and Hunter Biden is just the tip of it.
