Here is an apt passage

This is a very good passage to mark todays events in England. I hope this line resounds in the Brits today:

And you, good yeoman,
Whose limbs were made in England, show us here
The mettle of your pasture; let us swear
That you are worth your breeding; which I doubt not;
For there is none of you so mean and base,
That hath not noble lustre in your eyes.

And I think this Winston Churchill quote is quite apt as well:

We have before us an ordeal of the most grievous kind. We have before us many, many long months of struggle and of suffering. You ask, What is our policy? I will say; "It is to wage war, by sea, land and air, with all our might and with all the strength that God can give us: to wage war against a monstrous tyranny, never surpassed in the dark lamentable catalogue of human crime. That is our policy." You ask, What is our aim? I can answer with one word: Victory - victory at all costs, victory in spite of all terror, victory however long and hard the road may be; for without victory there is no survival."
