From The New Republic:

The 7/7 bombings were not the work of foreign terrorists, [Londonistan author Melanie] Phillips points out, but of men born and raised in the British welfare state.

Phillips also documents how leaders in Britain's government, media, and religious establishments have abdicated the defense of that great British invention, liberalism, in order to appease a sizeable domestic Muslim population....

What are the causes of this intellectual malaise and these security oversights? Phillips names several culprits, some more convincing than others. Foremost is the country's intellectual and legal capitulation to multiculturalism and European "human rights" dogma....

Phillips also argues that due to post-imperial guilt and the general takeover of the country's vital institutions by the left, Britain has lost its sense of self, allowing many Muslims to reject what should otherwise be obvious assumptions in the current debate over what should constitute "Britishness." This may explain why the English flag is hard to find in modern-day Britain. To a large portion of the country's educated, cosmopolitan citizens, the very display of the cross of St. George is immediately associated with right-wing movements and represents a throwback to England's imperial past. As an American living in London at the time of the 7/7 bombings, what most shocked me about the British response was the lack of patriotism expressed by both British leaders and everyday citizens. It was a silence that stood in stark contrast to the patriotic displays that were common in the United States after September 11. Only now with Britain in the World Cup can English flags be seen in abundance [Link].
