In an ongoing campaign that seeks to influence congressional and other political debates to stoke anti-Ukraine sentiment, Kremlin-linked political strategists and trolls have written thousands of fabricated news articles, social media posts and comments that promote American isolationism, stir fear over the United States’ border security and attempt to amplify U.S. economic and racial tensions, according to a trove of internal Kremlin documents obtained by a European intelligence service and reviewed by The Washington Post.

One of the political strategists, for instance, instructed a troll farm employee working for his firm to write a comment of “no more than 200 characters in the name of a resident of a suburb of a major city.” The strategist suggested that this fictitious American “doesn’t support the military aid that the U.S. is giving Ukraine and considers that the money should be spent defending America’s borders and not Ukraine’s. He sees that Biden’s policies are leading the U.S. toward collapse.”

The documents — numbering more than 100 and dating between May 2022 and August 2023 — were provided to The Post to expose Kremlin propaganda operations aimed at undermining support for Ukraine in the United States, as well as their scale and methods. The files are part of a series of leaks that have allowed a rare glimpse into Moscow’s parallel efforts to weaken support for Ukraine in France and Germany, as well as destabilize Ukraine itself.
