Of course it's not a good idea.
But direct tampering is probably considered an act of war. How long are we just gonna give Russia a pass?
There is no evidence of direct tampering and unlikely there ever will be.
Propaganda first and foremost is not direct tampering, it's Russia using its influence to sway opinion and way of thinking. This is not unique to Russia, U.S does it, China does it.
Even cyber-related attacks are difficult to prove as direct tampering, since you need intelligence elsewhere to confirm it's mandated by the government. For example, a DDoS attack can occur right now that disrupts part of the U.S internet infrastructure, there would be no way to prove it was a mandate by the Russian government based on origin for example, since they're botnets and they are located all over the world, you could see a lot of Chinese IP addresses, doesn't mean it's China, you could see a Russian botnet, doesn't mean it's mandated by Russia.
Same goes with hacking, you need to prove that it's mandated by the government, just because they're Russian hackers doesn't mean it's coming from the government, hackers can even be mandated by foreign governments.
You need to gather intelligence and infiltrate through other means like spies in foreign intelligence agencies, otherwise it's difficult to find evidence with this sort of thing.
And to find intelligence suitable and not sensitive for the public is even more difficult.
A recent similar example: Breitbart trying to push into Europe, propaganda, sway opinion, is it necessarily mandated by the U.S government?
