Terrorists dont care about the content of the G8 meeting.. but terrorists DO care about media exposiur...
The G8 has drawn the attention of almost all of the worlds medias to the UK and all the leaders are in the UK. Its right next door to where all the leaders are, its damn close, and its in a media exposed area of the world. So yeah the terrorist would care about the G8 in that aspect.
Though UK beeing the "next target" really isnt a suprice given the political history the UK has over the last 10s of years, beeing brothers in arms with the US.
