It seems to me that interfering in a foreign election should be understood to be grounds for war.
Yes, and the EU, due to this fragmentation, seems to be a fertile playground for all this unacceptable interference by foreign powers.
If this were really taken seriously there would be much more war.
Russia and China are definitely interfering in the US (to spread discord, ex https://en.wikipedia.org/wiki/Chinese_interference_in_the_20...), so should the US formally declare war against them?
What I do think is that nations should 1) interfere back, and 2) make their citizens more resilient to foreign propaganda. And I specifically don't mean building a firewall. In fact do the opposite: if a firewalled nation is leaking out propaganda, ensure firewall-breaking tools leak in.

Requires a rigorous definition of interference.
The allegations here—trying to catch politicians on tape being sleazy and then releasing them with sketchy editing-doesn’t seem to rise to the level of calling for a kinetic response.
