Not quite. Indochina was a French colony which rebelled and escalated into open conflict. The rebellion was successful, the French were expelled, and Vietnam was formed.
However conflict in the area continued as a civil war between the two dominant factions in Vietnam (communist vs capitalist) for control of the new country.
The US intervention was a failed attempt at suppressing the communist faction.
Gaza is different in that it was conquered by Israel during their war with Egypt. The Israelies even started building settlements there.
Israel then got out of Gaza and removed all their settlers as part of a peace accord (if memory serves).
However Gaza never really accepted peace with Israel and kept on attacking them, culminating in the Oct 7th attack that got us in this mess.
