They weren’t in NATO then. Now we have to go to war so they can act tough... even though they let the Russians rule over them for two generations. WW3 could happen over this?! GTFOH
Russia knows good and well that Estonia has a mutual defense pact with the USA. If they attack our ally, then Russia will be the ones who started World War III so they could “act tough.” How would they react if we attacked their CSTO allies like Belarus or Uzbekistan? It would mean war.
