KLM Flight 65 was a commercial flight between Los Angeles and Amsterdam that became one of the major turning points in recent U.S politics. The flight left Los Angeles with nothing special to report, until over the Great Lakes of Ontario, where a deflagration occured above the right wing of the aircraft. A terrorrist belonging to the organisation Boko Haram had managed to light a makeshift bomb in his shoe, which blew up a part of the aircraft and shredded some of the right wing. Having lost control over part of the hydraulics and little control over the right engine, the pilots opted for an emergency landing at Minneapolis Airport. However, they wouldn't be able to make it and settled for a field 114km north of the airport. The aircraft was smashed into several pieces on touching the ground, but nevertheless 157 people survived the intital crash, including both pilots. 9 passengers would unfortunately die at the site, while a further 8 would die in hospital.
The attack was claimed by the terrorrist organisation Boko Haram, which operated in the highly unstable Bornu Emirate. The EDF had begun an intervention in the region, but the U.S had declined to participate in the U.N-mandated intervention despite their recent interest in the region as part of their follow-up to the Millenium Attacks fourteen years earlier. The Social-Liberal party still proned non-intervention in the African region, but most of the Liberty and Radical parties would back up the intervention idea.
While they stayed high in the polls for the 2016 election, the Social-Liberal party would fall down and lose several states in the 2016 election due to their non-interventionist attitude amongst other things. The Liberty Party immediately passed a law after coming to power, making the United States join the EDF-led coalition against Boko Haram, and in April 2016, the first U.S soldiers landed in Africa in order to wage war since the Barbary Coast Wars.
