“We are fully aware that war is not the only way to defend our values. But if those values are fundamentally endangered, as is the case today, then war is the only way to defend them. Everything that hinders us in our effort to defend ourselves is an injustice. We did not want this war, it was thrust upon us, like all others. Defending one's people is a holy duty”

2013, Second Inaugural Address (January 2013)
Context: We will defend our people and uphold our values through strength of arms and rule of law.  We will show the courage to try and resolve our differences with other nations peacefully –- not because we are naïve about the dangers we face, but because engagement can more durably lift suspicion and fear. America will remain the anchor of strong alliances in every corner of the globe.  And we will renew those institutions that extend our capacity to manage crisis abroad, for no one has a greater stake in a peaceful world than its most powerful nation. We will support democracy from Asia to Africa, from the Americas to the Middle East, because our interests and our conscience compel us to act on behalf of those who long for freedom.  And we must be a source of hope to the poor, the sick, the marginalized, the victims of prejudice –- not out of mere charity, but because peace in our time requires the constant advance of those principles that our common creed describes: tolerance and opportunity, human dignity and justice.

Context: The liberties of our Country, the freedom of our civil constitution are worth defending at all hazards: And it is our duty to defend them against all attacks. We have receiv'd them as a fair Inheritance from our worthy Ancestors: They purchas'd them for us with toil and danger and expence of treasure and blood; and transmitted them to us with care and diligence. It will bring an everlasting mark of infamy on the present generation, enlightened as it is, if we should suffer them to be wrested from us by violence without a struggle; or be cheated out of them by the artifices of false and designing men. Of the latter we are in most danger at present: Let us therefore be aware of it. Let us contemplate our forefathers and posterity; and resolve to maintain the rights bequeath'd to us from the former, for the sake of the latter. — Instead of sitting down satisfied with the efforts we have already made, which is the wish of our enemies, the necessity of the times, more than ever, calls for our utmost circumspection, deliberation, fortitude, and perseverance. Let us remember that "if we suffer tamely a lawless attack upon our liberty, we encourage it, and involve others in our doom." It is a very serious consideration, which should deeply impress our minds, that millions yet unborn may be the miserable sharers of the event.
