Why was the colonization movement flawed?

it was flawed because the native americans. This is because they owned the land and lived there for years, so they would fight the colonists and the colonists didn't know the land so therefore they were bond to lose.

i believe the correct answer is option b. most eastern european nations joined nato.

though i could be wrong, option d. the eastern european nations were granted complete independence, would be another choice.

hope this ! : )

definitely a for sure. ill see and update if i get the answer
