What are 3 reasons to support manifest destiny

  Three Reasons to support Manifest destiny;

1.It gave an advantage for leeway to exchange and industry from different spots.  

2.It expanded products, administrations, and riches, by multiplying the land region of the U.S.  

3.It made ready for Americans to share their way of life.  

So by supporting this Manifest Destiny the Nation will spread its obligation to impact even past its mainland limits to "the Far East, Asia, and the Caribbean and Pacific areas".

In this way, Manifest Destiny reflected both the sentiments of pride that described "American Nationalism in the mid-nineteenth century" and "the optimistic vision of social flawlessness through God and the congregation".

unless they converted, many non-christians (mainly jews and muslims) were persecuted

no because it could make the world a terrible place to live in.
