In what way were korea and germany similar after ww2? 1) they refused to align with the superpowers 2) their former empowers stood trial for war crimes 3) both remained divided during the cold war 4) ethnic tensions threatened civil war in each country

The answer I have confidence is answer 3. After the wars the Berlin wall and the 34th parallel South were used as forms of barriers of guarded protection against the "enemy force", yet during World War 2, Germany united and managed to dominate Europe and many other countries, meanwhile South and North Korea used to be united until August 15, 1945 when South and North Korea divided based on their form of Government, North Korea being communist while South Korea staying Democratic.
