Well, I think she's coming from John Quincy Adams point of view.
..."words have meaning. To declare that it is now the policy of the United States to eradicate tyranny in the world, that we are embarking on the greatest crusade in the history of freedom, and that the survival of American liberty is dependent on the liberty of every other nation--seemed to me, and seems to me, rhetorical and emotional overreach..."
Compare her argument to Adams 1821 speech:
Monsters to Destroy
John Quincy Adams

"...Let our answer be this: America, with the same voice which spoke herself into existence as a nation, proclaimed to mankind the inextinguishable rights of human nature, and the only lawful foundations of government. America, in the assembly of nations, since her admission among them, has invariably, though often fruitlessly, held forth to them the hand of honest friendship, of equal freedom, of generous reciprocity.
She has uniformly spoken among them, though often to heedless and often to disdainful ears, the language of equal liberty, of equal justice, and of equal rights.
She has, in the lapse of nearly half a century, without a single exception, respected the independence of other nations while asserting and maintaining her own.
She has abstained from interference in the concerns of others, even when conflict has been for principles to which she clings, as to the last vital drop that visits the heart. She has seen that probably for centuries to come, all the contests of that Aceldama the European world, will be contests of inveterate power, and emerging right. Wherever the standard of freedom and Independence has been or shall be unfurled, there will her heart, her benedictions and her prayers be. But she goes not abroad, in search of monsters to destroy.
She is the well-wisher to the freedom and independence of all.
She is the champion and vindicator only of her own.
She will commend the general cause by the countenance of her voice, and the benignant sympathy of her example.
She well knows that by once enlisting under other banners than her own, were they even the banners of foreign independence, she would involve herself beyond the power of extrication, in all the wars of interest and intrigue, of individual avarice, envy, and ambition, which assume the colors and usurp the standard of freedom. The fundamental maxims of her policy would insensibly change from liberty to force....
She might become the dictatress of the world. She would be no longer the ruler of her own spirit...."
