The Northern press, as a whole, did not discourage these claims; a portion of it always magnified rebel success and belittled ours, while another por… - Ulysses S. Grant

With a soldier the flag is paramount. I know the struggle with my conscience during the Mexican War. I have never altogether forgiven myself for going into that. I had very strong opinions on the subject. I do not think there was ever a more wicked war than that waged by the United States on Mexico. I thought so at the time, when I was a youngster, only I had not moral courage enough to resign. I had taken an oath to serve eight years, unless sooner discharged, and I considered my supreme duty was to my flag. I had a horror of the Mexican War, and I have always believed that it was on our part most unjust. The wickedness was not in the way our soldiers conducted it, but in the conduct of our government in declaring war. The troops behaved well in Mexico, and the government acted handsomely about the peace. We had no claim on Mexico. Texas had no claim beyond the Nueces River, and yet we pushed on to the Rio Grande and crossed it. I am always ashamed of my country when I think of that invasion. Once in Mexico, however, and the people, those who had property, were our friends. We could have held Mexico, and made it a permanent section of the Union with the consent of all classes whose consent was worth having. Overtures were made to Scott and Worth to remain in the country with their armies.
The Mexicans are a good people. They live on little and work hard. They suffer from the influence of the Church, which, while I was in Mexico at least, was as bad as could be. The Mexicans were good soldiers, but badly commanded. The country is rich, and if the people could be assured a good government, they would prosper. See what we have made of Texas and California — empires. There are the same materials for new empires in Mexico. I have always had a deep interest in Mexico and her people, and have always wished them well. I suppose the fact that I served there as a young man, and the impressions the country made upon my young mind, have a good deal to do with this. When I was in London, talking with Lord Beaconsfield, he spoke of Mexico. He said he wished to heaven we had taken the country, that England would not like anything better than to see the United States annex it. I suppose that will be the future of the country. Now that slavery is out of the way there could be no better future for Mexico than absorption in the United States. But it would have to come, as San Domingo tried to come, by the free will of the people. I would not fire a gun to annex territory. I consider it too great a privilege to belong to the United States for us to go around gunning for new territories. Then the question of annexation means the question of suffrage, and that becomes more and more serious every day with us. That is one of the grave problems of our future.

Let us labor to add all needful guarantees for the more perfect security of free thought, free speech, and free press, pure morals, unfettered religious sentiments, and of equal rights and privileges to all men, irrespective of nationality, color, or religion.

Encourage free schools and resolve that not one dollar of money appropriated to their support no matter how raised, shall be appropriated to the support of any sectarian school...Leave the matter of religion to the family circle, the church & the private school support[ed] entirely by private contribution. Keep the church and state forever separate.
