That only postpones the problem for a few years, unless you establish a permanent military presence.
The US can keep 100,000+ soldiers on the ground for 7 years, have all of its top military brass focus on that conflict, fight cleverly and aggressively against the opposition, lead the country through the process of drafting a constitution and holding elections, train the new military and police forces, spend tens of billions of dollars helping to build the country’s infrastructure (in addition to hundreds of billions of dollars of military spending), gradually remove its troops in an orderly fashion as negotiated with the country’s new government, and still have everything go horribly within a couple years of leaving.
