Pacifism is like when you don't want anyone to fight or hurt each other, and you want to solve problems in peaceful ways.
In the United States, some people believe in pacifism because they think war is bad and causes a lot of harm. They believe that violence only leads to more violence, and that it's better to find other solutions to conflicts.
Pacifism has been an important part of American history for a long time. There were people who opposed the American Revolution and the Civil War because they didn't want to fight. During World War I and World War II, there were pacifist groups who protested against the wars and refused to serve in the military.
Even today, there are still people who believe in pacifism and work to promote peace. They might organize protests, write letters to politicians, or support organizations that work for peace around the world.
While pacifism is not a widely adopted philosophy in the United States, it is an important perspective that promotes discussion and debate over different solutions to conflicts.
