We've been doing it for a Century, ever since the Progressives took over.
Nation Building is fine, but you can only do it with complete capitulation by the host country. Unless you are will to do what it takes to completely destroy opposition, it will never work. Examples
Phillipines - we brutalized the shit out of the opposition until they gave up and we colonialized it.
WWI - Failed to fully defeat or occupy the enemy, we get to fight them again
WWII - Complete destruction, Nation Building works
Korea - South Korea completely capitulated to the US/UN as they knew they had to pick a ruler Commies or Progs
Vietnam - tried to Nation Build while fighting, didn't work
remainder of wars, see above
