WW3. There's a code to it. I mean it caused WW1 supposedly.

Look at what happened with Iran. Drone kill not subtle. It should have caused a war. Instead USA took a direct missile hit after. When was the last time a nation targeted a USA base directly and there wasn't a war. That was it. They assassinated a general.

Internally they haven't got protections afforded by the nation. But if another nation target's professionally what happens. Conflict. There are grey area's to be exploited and lines crossed on any strategy.

But there's often much bigger fallout if it's direct.
