“Which of you, wishing to build a tower, does not first sit down and calculate the cost, to see if he has enough to complete it?” Gospel of Luke 14:28 This simple yet profound question posed by Jesus to his disciples echoes as a timeless warning when faced with decisions that determine the fate of nations. In the context of Germany’s “Zeitenwende”—the so-called “historic turning point” marked by the permanent deployment of troops abroad—this verse urges us to reflect carefully on the consequences of our military and geopolitical actions. The construction of a “tower”—in this case, the structure of international security and order—cannot be entrusted to impulsiveness or mere will to power. It requires wise planning, a clear assessment of risk, and, above all, the awareness that every decision may lead to an escalation of unforeseeable proportions.
