Ken,
As Mike has said, there is plenty of blame to be shared by both parties in this. Personally, I find the actions of both sides beyond contempt.
However, it is too easy to be diverted by debating the political rights and wrongs, whilst in the real world ordinary men women and children are suffering under the most appaling circumstances. This is what needs addressing now. My decision to sign the petition was wholly apolitical. For me, it is about doing what we can to stop the human suffering NOW. On that basis, discussing the rights and wrongs, in an effort to determine which side is worse, or less bad, feels uncomfortably like 'fiddling whilst Rome burns'.
