That's a hypothetical, not an example. An example would be "US has been worried for years that Russia has been influencing US politics, now we see Russia invade Ukraine and US supports Russia"

Instead, what do we actually see? We see people claiming for years that Russia has been influencing US politics, yes the US has contributed more than the entirety of the european union combined to aid Ukraine in war efforts. In fact, some accounting suggests the US has donated more to Ukraine than Russia has spent on the war itself.

So where are these examples of successful spying/data turned into action or battlefield advantages? There's certainly no shortage of spying.
