Carl K. Kabat OMI (October 10, 1933 – August 4, 2022) was an American priest of the Catholic religious order Missionary Oblates of Mary Immaculate, best known for his eccentric, nonviolent protests against nuclear weapons.

[6] On September 9, 1980, Kabat and seven others (known as the Plowshares Eight) entered the General Electric Re-entry Systems Building in King of Prussia, Pennsylvania, where Mark 12A reentry vehicles were made.

[5] The story is partly told in the book ARISE AND WITNESS: Poems by Anne Montgomery, RSCJ, About Faith, Prison, War Zones and Nonviolent Resistance, published in 2024.

On April 10, 1990, the Plowshares Eight were resentenced by the Pennsylvania Court of Common Pleas in Norristown and, with neither the prosecutor nor General Electric making any recommendations or asking reparations, paroled for up to 23½ months in consideration of time already served in prison.

Judge James Buckingham considered statements by the defendants, attorney Ramsey Clark, Dr. Robert Jay Lifton, and Professors Richard Falk and Howard Zinn, placing the crime in the context of the common plight of humanity, international law, America's long tradition of dissent, and the primacy of individual conscience over entrenched political system.

On December 13, 2013, Kabat and five other protestors were found guilty of again trespassing at the Kansas City Plant, but were given the unusual sentence of writing essay responses to questions posed by the judge.
