What churchill meant when said if they become divided catastrophe may iverwhelm us all?

When Churchill warned that division could lead to catastrophe, he was emphasizing the importance of unity, especially during times of crisis. He believed that disunity among nations, particularly in the face of threats like fascism during World War II, could result in devastating consequences for everyone. His statement served as a call to solidarity, urging countries to come together to confront common dangers rather than allowing internal divisions to weaken their collective response.
