I sent this email to my MP Dr Phillip Lee in Bracknell tonight.
"The use of nerve gas is Syria is rightly being condemned internationally and that is no doubt that the Assad regime is oppressive, brutal and vile.
Unfortunately, many of the rebels groups are backed by Al Qaeda and are equally as bad.
None of our military adventures this century has had a good outcome, in Iraq, Afghanistan or more recently Libya. Our approval of a regime change in Egypt has also not led to a good result with the Muslim Brotherhood being voted into power and then removed by force where they pushed the country against the majority's wishes towards a much more radical version of the Islamic religion.
Although I can see the temptation of punishing Assad for the use of chemical weapons to send a message to other dictators that this is unacceptable behaviour, I can't see how this is going to make things better in Syria. Once we start there are real dangers that we will make things worse, with our missiles killing innocent civilians, either accidentally or if Assad uses them as human shields, thus adding to the casualties. With no clear objectives or reliable rebel groups to back to guarantee a better future for Syria, a regime change may well make things much worse and there is real danger of mission creep where we get more and more deeply involved in trying to force a more favourable outcome for the majority.
If I thought that our involvement would improve the situation and provide a better future for the Syrians I would back military intervention, but in the present circumstances, I feel us getting involved will just make things worse and therefore I urge you to vote against any military intervention there at this time."
I corresponded with him before and he has always taken the time to reply, but he is very much a party man, so I will follow how he votes in Thursday's debate with interest.
