Sgt. Slaughter

Context: After WrestleMania VI, Slaughter sent a letter to Vince McMahon saying he loved the program and was interested in returning. McMahon told Slaughter he wanted a heel, and his new gimmick would be that Slaughter turned on the United States due to its acceptance of the Russian Nikolai Volkoff. According to Slaughter, he found it difficult to do the anti-American promos associated with this gimmick. The August 1990 invasion of Kuwait by Ba'athist Iraq triggered a political crisis that would lead to the 1991 Gulf War, in which Kuwait was freed by a U.S.-led military coalition. A decision was made to have Slaughter support the Iraqi cause, not for the actual political reasons, but more for the fact that Slaughter liked "brutality" and the Iraqi government was "brutal" while the US regime was said by Slaughter to have become "soft" and "weak". Slaughter aligned himself with a kayfabe Iraqi military general, General Adnan (his old rival who left the AWA shortly after Slaughter did), and entered a feud with Volkoff (which saw Slaughter win the majority of their encounters at house shows), leading to a match at that year's Survivor Series which saw The Alliance (Volkoff, Tito Santana, and The Bushwhackers) defeat The Mercenaries (Slaughter, Boris Zhukov, and The Orient Express). As part of his character change, Slaughter began wearing Arab headdresses to the ring, adopted the Camel Clutch as one of his finishers, and was (kayfabe) photographed meeting with Saddam Hussein. Slaughter also infamously adopted a move where he would grind the tip of one of his knuckles into his opponent's temple (the childhood noogie). It was reported that while Slaughter was portraying a turncoat, he had received numerous death threats and could not go anywhere in public without wearing a bullet-proof vest and had to be surrounded with security personnel at all times. According to Slaughter, Vince asked him to burn the American flag, but Slaughter refused to, so Slaughter suggested he burn Hulk Hogan's shirt. As 1990 ended, Slaughter began challenging for the WWF World Heavyweight Championship that had been held by The Ultimate Warrior since WrestleMania VI. Slaughter got his chance at the Royal Rumble in January 1991, days after the Gulf War air campaign had begun. He defeated the Warrior when "Macho King" Randy Savage, who had also been feuding with the Warrior at the time, struck the champion in the head with his royal scepter. Slaughter thus became the thirteenth WWF World Heavyweight Champion and was immediately challenged by Royal Rumble winner Hulk Hogan, who was furious that Slaughter had (kayfabe) desecrated the American flag (off-screen) as part of his victory celebration. Hogan demanded a match against Slaughter at WrestleMania VII in Los Angeles, California, and Slaughter accepted. Slaughter was defeated by Hogan, thus losing his championship. After WrestleMania Slaughter introduced his newest ally, Colonel Mustafa (The Iron Sheik, Slaughter's old nemesis). Slaughter and company went on to feud with Hogan for months, including having a three-on-two handicap match at SummerSlam 1991, which saw the team of Hulk Hogan and the Ultimate Warrior prevail over Slaughter, Adnan, and Mustafa.
