Why go anywhere? Countless non-Muslim countries far more dangerous than Tunisia and other North African countries, yet British tourists flock there. Thailand for example.
As for your second paragraph, utter madness. You think furthering a divide with the Arab world and its people will be useful in some way? Beggars belief, we need greater solidarity, not less, with that part of the world. Why on earth do you believe the likes of UAE should take responsibility for the actions of a rogue terrorist in Tunisia anyway?!
"Greater solidarity" ?
Since the Tunisia killing of Brits have you read or heard anything from the Muslim community over here? Any condemnation from any Muslim MP, or any leading figure, Iman etc. How about the outspoken Baroness Warsi?....solidarity, the silence is deafening.
