“The Declaration of Independence was a source of inspiration to believe in ideals that transformed us from Jews to Israelis. … I am asking today with deep sorrow: Can we, despite all our achievements, ignore the intolerable gap between what the Declaration of Independence promised and what was fulfilled, the gap between the idea and the realities of Israel? Does the condition of occupation and domination over another people fit the Declaration of Independence? Is there any sense in the independence of one at the expense of the fundamental rights of the other? Can the Jewish people whose history is a record of continued suffering and relentless persecution, allow themselves to be indifferent to the rights and suffering of a neighboring people? Can the State of Israel allow itself an unrealistic dream of an ideological end to the conflict instead of pursuing a pragmatic, humanitarian one based on social justice. I believe that despite all the objective and subjective difficulties, the future of Israel and its position in the family of enlightened nations will depend on our ability to realize the promise of the founding fathers as they canonized it in the Declaration of Independence. I have always believed that there is no military solution to the Jewish Arab conflict, neither from a moral nor a strategic one and since a solution is therefore inevitable I ask myself, why wait?”

Context: The founding of our Nation was more than a political event; it was an act of faith, a promise to Americans and to the entire world. The Declaration of Independence declared that people can govern themselves, that they can live in freedom with equal rights, that they can respect the rights of others.
In the two centuries that have passed since 1776, millions upon millions of Americans have worked and taken up arms when necessary to make that dream a reality. We can be extremely proud of what they have accomplished. Today, we are the world's oldest republic. We are at peace. Our Nation and our way of life endure. We are free.

Context: And do not think, my boy, that because I, impulsively broke forth in jubillations over Shakspeare, that, therefore, I am of the number of the snobs who burn their tuns of rancid fat at his shrine. No, I would stand afar off & alone, & burn some pure Palm oil, the product of some overtopping trunk. — I would to God Shakspeare had lived later, & promenaded in Broadway. Not that I might have had the pleasure of leaving my card for him at the Astor, or made merry with him over a bowl of the fine Duyckinck punch; but that the muzzle which all men wore on their soul in the Elizebethan day, might not have intercepted Shakspers full articulations. For I hold it a verity, that even Shakspeare, was not a frank man to the uttermost. And, indeed, who in this intolerant universe is, or can be? But the Declaration of Independence makes a difference.—There, I have driven my horse so hard that I have made my inn before sundown.

Letter to John Adams (31 March 1776), published in Familiar Letters of John Adams and his wife Abigail Adams (1875) edited by Charles Francis Adams, p. 147
Context: I long to hear that you have declared an independency. And by the way, in the the new Code of Laws which I suppose it will be necessary for you to make I desire you would Remember the Ladies, and be more generous and favourable to them than your ancestors. Do not put such unlimited power into the hands of the Husbands. Remember all Men would be tyrants if they could. If particular care and attention is not paid to the Ladies we are determined to foment a Rebellion, and will not hold ourselves bound by any Laws in which we have no voice, or Representation.
That your Sex are Naturally Tyrannical is a Truth so thoroughly established as to admit of no dispute, but such of you as wish to be happy willingly give up the harsh title of Master for the more tender and endearing one of Friend. Why, then, not put it out of the power of the vicious and the Lawless to use us with cruelty and indignity with impunity? Men of Sense in all Ages abhor those customs which treat us only as the vassals of your sex; regard us then as Beings placed by Providence under your protection, and in imitation of the Supreme Being make use of that power only for our happiness.

Context: Three of my ancestors signed the Declaration of Independence. It's just that any system of government has it pluses and minuses and it's important to understand the system of government you do live under so that you can protect it.
