Martin Luther King Jr believed that the US had not yet fully realized the ideals?

Martin Luther King Jr. believed that the United States had not fully realized its foundational ideals of equality, justice, and freedom for all citizens, particularly for African Americans. He argued that systemic racism, economic inequality, and social injustice continued to undermine the nation's commitment to these principles. King envisioned a society where people would be judged by their character rather than the color of their skin, and he advocated for nonviolent resistance as a means to achieve true equality and civil rights. His dream was for America to live up to its promises and ensure that all individuals could enjoy the rights and opportunities guaranteed in the Constitution.
