Answer:
The campaign stroke for the peace of the world where people are having the same thoughts.
Step-by-step explanation:
Speaking from my point of view (as a Vietnamese), the campaigns around the world calling to end the Vietnam war has awakened people around the world who have the same ideology to stop the war that kills so many innocent people. This ideology already existed in many people, but many were afraid to stand up in different countries. The movement added a stronger human strength to fight for world peace.
