Good luck and may God and of course the US stand beside you. I think the terrorists forgot that London has been through this before and stood strong.
The English have been through a lot worse. The amount of damage in this attack is not significant in either a military sense or in an economic sense. It may have some propaganda value, except the English still are allowed pitchforks and hoe handles and aren't about to give in to a group of 20 young people.
