What if Russia invades due to referendum being hold?

Is it qualifying as "Georgia goes to war with Russia"?

Some online commentators have indicated that talk of a referendum is a political stunt, intended to defuse pro-war sentiment. That sort of referendum can backfire (ala Brexit), but this time one can expect the Kremlin's propaganda to be tipping the scales against anything interesting happening.

How will this resolve if the US state does so?

@LivInTheLookingGlass They could pass an amendment technically
