"Operation “Nitro Zeus” illustrates this thinking. As Buchanan explains, in the early stages of the Obama Administration, U.S. hackers went on an expansive hunt for “zero-day” vulnerabilities in Iran’s strategic infrastructures. The raid targeted the Fordo nuclear facility that Washington suspected was purifying uranium to weapons grade. But that was not all. The United States also penetrated Iran’s financial, transportation, and air defense systems. The invaders acted in anticipation of the possible failure of diplomatic efforts to curtail Iranian enrichment activity peacefully. They crafted weapons of war even as they strived to avert it."
