What were some pros and cons of supporting the vietnam war?

It's a much debated factor, of what were the Pros and Cons on a war of wrong by the US. In my opinion, these are the Pros and Cons. 

Pros:

The war made people feel obligated to serve their government even in the wrong

The war was conducted for means that the spread of Communism could be contained (This is towards your preference)

It was one of the most televised and known war at the time.

It helped modern day wartime Journalism 

CONS:

The government went into major debt because of their lose

The draft majorly threatened the lower and middle class 

There was no "Glory of War" due to photographed evidence

The government was looked down upon due to not being justifiable for their actions.
