The official object is to pop up the South Vietnamese Government, the US did that. Every single year US troop launch their objective in Vietnam, and every single year, the objective completed
US were never into "Getting rid of North Vietnam" because if that is the point, US troop would have been allowed to invade North Vietnam or at least Southern Cambodia. So, if you want the truth, the US War in Vietnam have no objective at all, the sole objective is to see how many casualty the US can cause in Vietnam and hopefully stop North Vietnamese from fighting.
So yes, we were there to kill people and kill people only, and if that is not for fun, then I don't know what is.

Why? When they cannot even nuke US. They don't even have long range missile to nuke Hawaii
Having nuke in North Korea present more of a problem in China than the US, well, China is the one bordering North Korea, not US, on the other hand, the US can squeeze their Southern Neighbour for more money, for THAAD and more military control. North Korea having nuke FAVOURS the US, why the US want to take them down?
