apparently it was collated by a dead ghoul (rest in piss) called Rudolph Rummel, who dedicated his life to this. Unsurprisingly he also supported the mass murder of Iraqis by the US government.
I looked this guy up assuming that he might have arrived via Operation Paperclip, but no, despite his name he was actually born in Ohio.
He tried to argue here that "democracies don't make war" and then said the US doing covert action against other countries doesn't count because "actchually the countries they targeted weren't democracies, and it was okay because gobbunism bad, also the CIA is bad and not democratic but they wouldn't do those things if they had more Democracy " Like he actually tried to redefine "war" as armed conflicts strictly between so that any suffering the US inflicts on other countries is justified because they are Spreading Democracy™ and aren't actually wars because the victim countries aren't "democracies."
Also apparently the US Civil War wasn't a war because the Confederacy "was not recognized by any major Power, which means that it was not recognized as an independent state."
