Dealings with the Science-side
Though America isn't a part of the Science-side, on its own it has been trying to develop esper powers on their own since the Cold War. Though, still behind Academy City in terms of technology, the United States is still one of the foremost powerful economic and military entities in the world.

Angel Fall Arc
Washington, D.C. is briefly seen in television, in the first season of the Toaru Majutsu no Index anime. Here, Shirai Kuroko's form is taken-up by the President of the United States of America, saying Barack Obama's famous line: Yes we can. Needless to say, Kamijou Touma, due to the effects of his Imagine Breaker making him unaffected by the spell, as well as being ignorant of the spell's affect, is completely shocked by discovery, leading him to believe that the recent switching of personalities and the inexplicable appearance of people he knows around him is not just a mere prank.

Tree Diagram Remnant Arc
The United States was one of the countries that launched spacecraft to retrieve the remains of the destroyed Tree Diagram.

Document of Constantine Arc
The Anti-Academy City riot occurred in west coast cities such as and. In Los Angeles, one side of a three-lane highway was completely filled with people. They were burning Academy City posters they had made and were ripping Academy City banners to shreds.

World War III
The United States of America, allied with the United Kingdom of Great Britain and Northern Ireland, and part of the science-side, takes part in the War, but their contributions are largely overshadowed during the event, due to Academy City's overwhelming technological superiority, as well as the appearance of a power they could not wholly understand, magic.

Hawaii Invasion Arc
Due to the strange movements of several people, including high government officials, President Roberto Katze leaves the side of his protection to investigate the mysterious occurrences. He would later be involved in trying to stop an invasion of Hawaii, and later the turning of the United States into a by Olay Blueshake with the help of GREMLIN and Trident. With the aid of the Kamijou Faction and the Dawn-Colored Sunlight, Roberto and the United States military was able to stop the invasion, though at a great cost, the volcano, Kilauea still erupted, furthering GREMLIN's plans.

Magic God Othinus Arc
Still reeling from the attack in Hawaii and with GREMLIN becoming even more brazen with their actions, the United States of America becomes involved in the opposition against GREMLIN, seemingly leading the international coalition, the Anti-GREMLIN Alliance, formed from various nations to oppose GREMLIN.

Kamijou Touma notes that the United States of America sets itself apart from the other dogmatic powers of the science and magic side by being the most rational. Indeed, it is Roberto who is the first one of the international coalition's leaders to lay down his pride and trust humanity that they will not give into the fear of the power of a magic god like Othinus.
