No evidence give. Disinformation outlets did not mention that the Worldwide Thread Assessment regarding Ukraine mentions that “Russia will continue its military, political and economic destabilization campaign against Ukraine to stymie and where possible reverse Kyiv’s efforts to integrate with the EU and strengthen ties to NATO”. Russia will also “work to erode Western unity on sanctions and support for Kyiv”.

Regarding President Poroshenko, the assessment states what is widely known, that popular frustrations with slow reforms, low living standards, perceptions of deepening corruption, and political polarization ahead of scheduled elections in 2019 could bring on early elections.

There is no mention of regime change or of a black mark against Poroshenko in the Assessment. Further debunking by Stopfake https://www.stopfake.org/en/fake-us-intelligence-finds-reasons-for-regime-change-in-ukraine/.
