I suppose that since July 2005 we have only had 2 terrorist in the UK (Glasgow and Exeter) both of which were classified as minor. So you could argue that our streets are pretty safe from International Terrorism
Well we had a few years of the IRA doing their thing and that was more or less put to bed by the peace initiatives. How many extremist-Muslim terrorist attacks did the UK have before we got involved in the wars in the Middle East?
I could understand wanting to go into Afghanistan and looking at security options in Pakistan...to find the Taliban and Osama and his cronies but I can't see what benefit we are having now whilst we stay there that will last 5 minutes once we've left (which we will though more of our forces will die & money will be spent before that happens).
Iraq was a terrible mistake based on war mongering and lies. I think there were other ways and means to marginalise and remove Madass Insane.
