I didn’t say anything about what NATO or Russia would do. I just know what the Estonians have as their main battle plan.
And I do not think the Russians will do that. They have shown how incompetent they are in Ukraine, especially with the corruption of many of the Generals. Russia would probably wait to see what NATO would do, then tell the Estonians they had better surrender or die.
Then Putin would send in the drones and missiles. Russia wants the infrastructure and the people. It is why Kiev wasn’t blasted in the first months.
