What was the name of the operation in 1986 authorized by President Reagan to strike England?

Operation El Dorado Canyon was the operation authorized by President Reagan in 1986 to strike targets in Libya, not England. The operation involved airstrikes aimed at military targets and locations believed to be associated with Libyan leader Muammar Gaddafi's support for terrorism. The operation was a response to incidents of Libyan-sponsored terrorism, particularly the bombing of a La Belle disco in West Berlin that killed U.S. service members.

The other options relate to different historical military operations. Operation Chariot refers to the Raid on Saint-Nazaire during World War II, Operation Rolling Thunder was a sustained bombing campaign during the Vietnam War, and Operation Market Garden was an unsuccessful WWII operation aimed at capturing bridges in the Netherlands. Each of these operations had distinct objectives and contexts that clearly differentiate them from Operation El Dorado Canyon.
