[Update: See the excellent response I received from my MP in the comments section below.]
I just sent the following to my MP. If you wish to take similar action, you can find out how to contact him/her here: http://www.parliament.uk/mps-lords-and-offices/mps/.
I urge you, as my MP, to vote against the UK taking military action against IS. I also urge you to read this MediaLens article on the issue: “The Purpose And The Pretence – Bombing Isis“.
There is no reason to believe that IS is any worse than other forces in the area and, in any case, it is highly unlikely that airstrikes would resolve anything. The only certain outcomes of the UK’s participation would be further civilian deaths and the transfer of public wealth into private hands (through the arms industry, at the very least). A likely outcome would be the generation of further so-called “terrorism”. (In reality, as I hope you will acknowledge, “terrorists” are simply our enemies du jour; to many we are the “terrorists”.
I would also suggest that you might like to refresh your memory of George Orwell’s 1984. The parallels with the present-day UK are striking. I shall not insult your intelligence by pointing them out for you.
Thak you for considering this. I look forward to your response.
