From a comment on Little Green Footballs:
For those of you who are anxious to know how the UK will react, we've been bombed for years by the IRA, and no-one spoke of quitting. Half of London and much of Coventry was flattened by the Luftwaffe a generation or two back, and no-one ran. Before that, in my grandparents' time, we were bombed by Zeppelins and didn't give in. We gave up appeasing after Czechoslovakia. There's no panic today, and there won't be, but we, all of us, are bloody angry. Al quaeda may think we're going to run up the white flag, but I promise you nobody else does.
For what it's worth, I sure as hell don't.
