Vietnamization of the war was the u. s. policy that required: south vietnamese troops to replace american troops cambodia and laos to be protected from the communists a peace treaty to protect north vietnam

Vietnamization of the war was the U.S. policy that required "South Vietnamese troops to replace American troops" since discontent was high in the US. 

In my honest opinion , i’d say franklin d roosevelt was a president that impacted our nation , i say this because fdr is voted among top three best us presidents and he was the longest serving president by 3 terms , usually presidents only supposed to have two terms increments of 4 years , equivalent to 8 years total before election time. and he established the fdic , through the 1933 banking act and he established the us , social security system , during his presidency, and established a national minimum wage , through the fair labor standards act , fdr led the allied coalition to victory in wwii and he played a major role in the creation of the united nations.

The coast of north america , basically yes newfoundland , i would say c , good luck
