In February 2014 a fire at Party of Regions headquarters in Kyiv revealed the "black ledger" or Manafort Papers. Ukrainian anti-corruption activists exposed the Putin-Manafort-Yanukovych plot. If Americans had paid attention, the Putin-Manafort-Trump plot might have been stopped.
When Russia launched the Trump-for-President active measure against the U.S., Trump began making public statements that repeated Kremlin talking points about Russia's invasion of Ukraine – such as nonsense about Crimea. I started writing in Aug 2015 about Trump as Putin's puppet.
Putin assigned Paul Manafort to be his "grey cardinal" or handler for Russia's asset Trump. At this point I was pretty much shouting for Americans to pay attention to Russia's war on Ukraine that was obviously expanding to the US. Many good Ukrainians gave the same warnings.
