The answer is Clinton in this particular instance.
Hardly. Ethnic violence in the Balkans and other former Soviet satellite states at the end of the Cold War...the failed Somalia mission...the rise of Islamic terrorist groups with the resources and means to strike on American soil.
On the economic front, America enjoyed a brief era of prosperity under Clinton, although arguably not because of anything he specifically did...however, the world stage is a completely different story, and if anything, Clinton, as did Bush Sr., failed to define America's role in a post Cold War world.
JFK...he comes off the list because of Bay of Pigs, a near nuclear slugmatch with the Soviets, Vietnam, etc.
Reagan...hard to say really...he certainly was a master of Cold War politics, but American wars on the periphery certainly layed the foundation for instability in many parts of the Third World.
A better question is not when the world was most safe, but rather which Presidents truly grasped and successfully mitigated threats to American interests.
I would say Lincoln and FDR are two Presidents who stand out as two noteable examples.
