Might be some Churchill speeches that fit the bill.

The Gettysburg Address is too short, 263 words http://en.wikisource.org/wiki/Gettysburg_Address?oldid=417591

Instead, I suggest President Franklin Delano Roosevelt’s speech after Pearl Harbor was bombed during World War II, asking Congress to declare war on Japan (517 words). http://en.wikisource.org/wiki/Pearl_Harbor_speech

Churchill’s we will combat on the beaches, we will never resign one. Do it. you may ought to do an excerpt however. the top? .: even however super tracts of Europe and various of previous and widespread States have fallen or could fall into the grip of the Gestapo and all the odious equipment of Nazi rule, we will no longer flag or fail. we will bypass directly to the top, we will combat in France, we will combat on the seas and oceans, we will combat with transforming into self assurance and transforming into power interior the air, we will shield our Island, besides the fact that the fee may be, we will combat on the beaches, we will combat on the touchdown grounds, we will combat interior the fields and interior the streets, we will combat interior the hills; we will never resign, and whether, which i do no longer for a 2d have self assurance, this Island or an excellent part of it have been subjugated and ravenous, then our Empire previous the seas, armed and protected by the British Fleet, could shop on the war, till, in God’s reliable time, the recent international, with all its skill and could, steps forth to the rescue and the liberation of the previous. gets me each and each time.

Here’s a list of speeches – pick your favourite 🙂

What about ‘I have a dream’ from Martin Luther King or ‘History will absolve me’ from Fidel Castro if you want something controversial 🙂

Patrick Henry’s “Give me Liberty, or give me death” speech is fairly short, and there’s a lot more to it than the last line. Trust me.

Lincoln’s Gettysburg Address has my vote.

definitely the gettysburg address. its famous for being short.
