The 40-year-old had replied to a fake ad that offered an underage girl for sex, and flew to the U.S. to meet with the agent – who was posing as the girl's father.
Incest-obsessed Ali arrived in the country with bondage tape, face masks, condoms, cameras and a laptop containing child porn all stashed away inside his luggage.
He told the undercover agent: "When you start with very, very, very young, you can mould them to believe anything and do anything."
Ali was arrested in Florida last April and pleaded guilty to his crimes last week.
Sheriff Wayne Ivey said: "It is truly unimaginable that monsters exist and walk among us with the purpose of victimising our most precious citizens."
Ali was jailed for 10 years.
