This is a headline quote in today's Metro free newspaper (London). It is from UK Prime Minister David Cameron. One of the things that provokes terrorism is our armed forces' presence in various countries. In particular, I believe I am right in saying, where this involves non-Muslims being in Muslim countries.
Of course, terrorist attacks, whether real or false flag, generate work for our security services, either setting up the false flag attacks or trying to prevent attacks. Is that really what 'Dave' meant?
