Innocent?
In 2003 the UK Labour government gave full military support to the US's illegal 'Shock and Awe' invasion of Iraq, which resulted in the deaths of up to 1 million civilians (mostly Muslims). In 2005 the British Labour Party was reelected with 35% of the popular vote.
Using present figures, 35% of British voters means around 14,000,000 people at least. So, under the best of circumstances, we have 14,000,000 people walking around in the UK, who support terrorist attacks on innocent civilians.
