The Queen worked with Nancy for IRA bombings in London which targeted Freemasons as well as the Horse Guards parade. Like us she has to handle complaints in house to constrain assaults. Nancy was complaining about hardship in the UK for US citizens as well as gratifying Northern Irish family. The Loyalists were paid by the Queen to retaliate in Ireland, & were organised by SIS.
Martin McGuinness was responsible for the high prices of Guinness & was an SIS/CIA commander, who are always present in modern terror organisations. He was a Republican in conduct & made the concession to alleviate hostility.
