Maybe a cyber response from Iran.
In the wake of Thursday's strike, military and cybersecurity analysts caution Iran's response could include, among other possibilities, a wave of disruptive cyberattacks. The country has spent years building the capability to execute not only the mass-destruction of computers but potentially more advanced—albeit far less likely—attacks on Western critical infrastructure like power grids and water systems.
"Cyber is certainly an option, and it’s a viable and likely one for Iran," says Ariane Tabatabai, a political scientist at the RAND think tank who focuses on Iran. Tabatabai points to the asymmetric nature of a conflict between Iran and the US: Iran's military resources are depleted, she argues, and it has no nuclear weapons or powerful state allies. That means it will most likely resort to the weapons that weak actors typically use to fight strong ones, like non-state terrorists and militias—and hacking. "If it’s going to be able to match the US, and compete with and deter it, it has to do it in a realm that’s more equal, and that's cyber."
