Not true. There have been TWO presidential elections since February 2014, the most recent in April 2019, when Zelensky was overwhelmingly elected.
And even then, there was NO overthrow in 2014---Comrade Putin's toadie Yanukovych abandoned the presidency in the middle of the night and fled to Russia, after which the Ukrainian parliament removed him from office and held a new election that spring.
There is no amount of lipstick you can put on this pig that will make it right. The US State Dept. also did it’s best to interfere with Minsk II.
It is very likely the US was involved in destroying the gas pipelines to Europe.
As a result, the former state of Ukraine is in imminent danger of being swallowed whole.
American influence on this situation has been of no legitimate benefit to anyone.
