UK prime minister David Cameron has said that intervention in Syria would be "fundamentally different" to Iraq in 2003.
First off, intervention would not be about regime change or even working more closely with the opposition. It would be a "response to war crime, nothing else". He added that the fact that the Syrian regime used chemical weapons against civilians on 21 August is "beyond doubt".
In addition, Cameron said that there was much greater unity on the need to take action. Unlike in Iraq, Europe, NATO and the Arab Leage are united in the opinion that those responsible for chemical attacks should be held accountable.
