Hold up, there's a HUGE difference between these two:
A: "Most people consider it an objective fact that Russia is a current geopolitical enemy to the US, it does some wacky shit, therefore if a foreign government is committing shenanigans there's a chance it's Russia."
B: "Most people consider it an objective fact that Russia has been somehow giving educational grants to US institutions with the explicit goal of installing a fifth-column of educators who will demoralize young US men with misandry."
Believing A does not imply B.
The parent-poster isn't being vague because the answer is obvious-and-accepted... they're being vague because they want to push the "foreign enemies in our colleges" meme without giving the audience any handles for critical-thinking.
I've yet to encounter a scenario in the last year where filling in that blank with "Russia" wasn't considered an objective fact by most.
