A figure that often gets overlooked is how many new wars Trump has entered into: 0.
Just look at how brilliantly he handled the situation with North Korea. Like he said, if a Democrat were President, the US would be at war with North Korea right now. The same goes for Russia.
And personally, i think its good that he has good relations with Putin and Ji Ji Ping. It means that as long as he is President, no wars will be fought among the world's mega powers.
I don't know enough history to say "all time", but within my lifetime? Absolutely.
