#2 Sgt Slaughter begs the U.S. for forgiveness after his heel run in 1990/1991
Sgt. Slaughter returned to the WWF back in 1990 as a heel, aligning himself with Iraq after the invasion of Kuwait. The company attempt to profit off of the conflict while also pushing the former Marine as an American hating Iraqi sympathizer definitely offended fans throughout the world.
However, after losing the WWF Championship to Hulk Hogan at WrestleMania VII and losing a handicap tag match with General Adnan and Colonel Mustafa against Hogan and the Ultimate Warrior, Slaughter immediately turned back to a face, with vignettes of Slaughter asking the fans for forgiveness, saying that he "wanted his country back."

Those two years were considered incredibly controversial for the WWF back in the day, and the fan base had an, understandably, difficult time accepting Sgt. Slaughter again.
