Which president declared an "Unconditional War on Poverty" in 1964?

Lyndon B. Johnson is credited with declaring an "Unconditional War on Poverty" in 1964 as part of his broader Great Society program. This declaration aimed to address and reduce poverty in the United States through various initiatives focusing on education, healthcare, and economic opportunity. Johnson's approach emphasized the government's role in providing support and resources to those in need, fundamentally reshaping social welfare programs and policies during his presidency.

Other presidents listed played significant roles in U.S. history and had various policies, but none made the specific and direct commitment to combating poverty in the same manner as Johnson did during the 1960s. For instance, John F. Kennedy laid the groundwork for social reform initiatives but did not launch a designated campaign against poverty during his presidency. Richard Nixon implemented some welfare reforms but focused more on other aspects of governance, and Ronald Reagan is often associated with reducing government assistance programs, rather than increasing efforts to combat poverty directly.
