A 1948 UNICEF photograph captured seven-year-old Tereska standing before a blackboard, asked to draw 'home.' Instead of a house, she sketched chaotic white chalk lines—frantic, reaching strokes that embodied absence rather than shelter. David 'Chim' Seymour documented the aftermath of war on Europe's traumatized children, but this image became iconic for what it revealed about unprocessed childhood horror.

Tereska survived the Warsaw Uprising at four when Luftwaffe bombs destroyed her family home. She suffered brain damage from shrapnel, lost her grandmother to bombing, and watched her father endure Gestapo torture. By 1948, PTSD remained undiagnosed—formally recognized only in 1980. These children were told to survive, be grateful, and move on, with no framework for processing what their nervous systems had absorbed.

The photograph reveals how unhealed collective trauma calcifies across generations. Tereska carried those fragmented lines for three decades, expected to function normally in Poland's post-war ruins while millions of other survivors did the same. Their children grew up in trauma's blast radius, then their children after them. The fear of annihilation becomes preemptive violence; hypervigilance becomes national policy.

Seventy years later, children in Gaza, Ukraine, and refugee camps draw similar fractured images when asked about home. The cycle continues because trauma unprocessed becomes ideology, policy, and inherited nervous system patterns. We have the language now—neuroscience, trauma research, intergenerational understanding—but whether we'll apply it determines what repeats.
