"No one is obligated to take him unless he is charged," Paskey said. "Ukraine wouldn't have to take him. No one else would want him."
The AP investigation revealed that Karkoc lied to American immigration officials to enter the United States after the war, saying he had no military experience and concealing his work as an officer and founding member of the SS-led Ukrainian Self Defense Legion. Records don't show Karkoc had a direct hand in wartime atrocities, but the evidence shows that he had command responsibility over a unit that massacred Polish civilians. Karkoc's family claims he was never involved in Nazi war crimes. Justice officials would not confirm whether the U.S. is investigating Karkoc.
Paskey said the U.S. could have a good denaturalization case against Karkoc, because prosecutors wouldn't have to prove he had a direct hand in war crimes. But the quickest — and perhaps only — way to remove him from the U.S. would be if he is charged criminally.
"Unless Poland or Germany decides to prosecute him," Paskey said, "he is likely to die in the United States."
