Why does Washington find it hard to beat Iranian influence? According to the State Department, it's because the U.S. doesn't use "political violence" in Iraq, a country that the U.S. famously invaded and occupied in 2003.
"Iran uses levers of power that we refrain from using (political violence, bribery) and has economic and cultural relationships we cannot replicate," says the State Department's Iraq Familiarization Course slideshow from 2020 and 2021, which it just released under the Freedom of Information Act (FOIA), along with several hundred pages of other training documents.
