Noninvolvement in world affairs is termed "isolationism".

Explanation:

Isolationism is a concept that designates a political inclination that defends the isolation and nonintervention of a country in international conjunctural issues. That is, putting it in simpler terms, isolationism proposes that a country does not intervene in any way in an external conflict that afflicts another nation or group of nations so that it does not end up affecting their interests.  

Basically, isolationism causes that the country that adopts this position is totally isolated from everything that happens in the rest of the world so that nothing affects it in its possible benefits.
