Trump says the State Department helped overthrow the Ukraine in 2014. I believe Trump, not you.
Trump is not our Dear Leader with whom we must always agree. He has made some ill-informed statements about Ukraine. But even if it were true, it has been made moot by the two subsequent elections. What may or may not have happened in 2014 is no justification for Russia's invasion eight years later. The truth is that Putin is upset that his own interference in Ukrainian with Yanukovych was thwarted. It is the hight of hypocrisy for Putin to complain about Yanukovych's removal when one of his stated war aims is to replace the elected Ukrainian government with a pro-Russian one acceptable to Moscow.
