A: rus*ia spends more money on military, thus making Sweden its protectorate. Finland's welfare is provided by the philippines who also spend more money on defense (probably, idk, you get my point)
B: like the time US deterred winter war that didnt happen
C: false. Countries like Finland and Sweden have always upheld militaries to protect themselves, alone, like we have done. Alone. Without US help despite relations, since neutrality is a thing. Look it up
D: god I wish, that would have meant my grandfather wouldnt have had to evacuate from karelia as a little boy while communists were raining arty on the train he managed to get himself into while his father stayed, fought and died. But actually US spent more money on military so it didnt happen. Actually no wars have been fought in countries allied with the US.
