Albert Gallatin’s thought about the idea of Manifest Destiny was: US should be superior.
Step-by-step explanation:
Abraham Alfonse Albert Gallatin was a Genevan-American politician who served as a Secretary of the Treasury in United States of America. He was also a linguist and diplomat.
In the year 1826-1827, he was appointed as the ambassador to the London government. He was generally known for his “Treaty of Ghent” which helps in ending up the War of 1812. Gallatin always wants America to be the major nation and should have efficient transportation arteries. So he proposed the idea of Manifest Destiny.
