Mike Waltz defended Trump's threat to 'knock out every single power plant' in Iran on ABC's 'This Week' Sunday, saying destroying such infrastructure is legally permissible. Waltz argued that 'attacking, destroying infrastructure that has clearly and historically been used for dual military purposes is not a war crime,' though international humanitarian law prohibits deliberately targeting civilian infrastructure without military objectives. The timing is critical: the ceasefire expires Wednesday April 22, 2026, making the threat directly tied to failed negotiations.
