It's a good one.
The final paragraphs:
Though it is not yet known with certainty precisely who is responsible, we do know terrorists’ intentions. They strike without warning and without regard for human life in the hope that they can frighten and intimidate free people -- to change our way of life. And they won't stop until their side or our side has prevailed.
But if these terrorists thought they could intimidate the people of a great nation, they picked the wrong people and the wrong nation. For generations, tyrants, fascists, and terrorists have sought to carry out their violent designs upon the British people only to founder upon its unrelenting shores.
Before long, I suspect that those responsible for these acts will encounter British steel. Their kind of steel has an uncommon strength. It does not bend or break.
The British have learned from history that this kind of evil must be confronted. It cannot be appeased. Our two countries understand well that once a people give in to terrorists’ demands, whatever they are, their demands will grow.
The British people are determined and resolute. And I know the people of the United States are proud to stand at their side.
