There is no absolute coordinate system in the universe. Everything is always in motion, relative to virtually everything else. You can be still relative to the surface of the Earth, but the Earth is rotating, and revolving around the Sun. The entire solar system is whizzing around at a faster relative velocity around the galactic center. We are moving away from galaxies near our observable horizon at tremendous velocities (expansion of the universe for that last example, which is a slightly different scenario, but still noteworthy).
Since there is no "absolute grid" to define location in space (location is determined relative to an object we refer to as "fixed" even though we know it is not) it is impossible to say what is still and what isn't. Relatively speaking, I have been in the same place my whole life, and the surface of the Earth beneath me, and the night sky above and below me, have been the only thing moving this entire time.

The UN wasn't really involved in the Vietnam war. It was more involved in the Korean war which happened a few years earlier. American's fear of commmunism seemed to be cemeted when North Korea attacked South Korea, America then asked the UN intervenean to stop the attack. Eventually they organised a military force to stop the attack.
