Trump makes plenty of hostile moves toward Russia of his own accord. This is compounded, however, when members of his cabinet, like CIA Director Gina Haspel start conniving to mislead Trump into taking even more hostile moves.
When the alleged Novichok poisoning happened in Salisbury in March of 2018, President Trump was not inclined to go along with recommendations within his cabinet to take a “strong option” to move against Russia.
Haspel was somehow “tasked” with convincing Trump to accept this move, and in doing so she showed Trump fake photographs of dead ducks, claiming that the ducks were poisoned in the “sloppy” Russian action.
This narrative centered on the fact that the poisoned Sergei Skripal was feeding ducks ahead of showing symptoms. He also interacted with some children at the time, and Haspel even had photos of “sick children.” There is no record that any children were sickened in the Novichok incident, and likewise there was never a single report of even one duck dying.
But fake photos work better than facts, ultimately, and Trump was quickly sold on taking the “strong option,” expelling a large number of Russian diplomats and closing a Russian consulate. This made 2018 a continuation of worsening US-Russia ties, which apparently was the goal of Haspel and others, but which they were only able to sell Trump on by lying about what actually happened.
