His point was that economic interdependence in the current age(1910-1860) meant that changing the international order by force of arms would not lead to a more favorable outcome for the aggressor. In fact, quite the opposite. The aggressor's economy would be wrecked even in victory no matter the length of the war. Economic isolation from world trade and credit would be devastating.
If he was claiming that war was impossible would he bother to write a book arguing that the benefits of war were not commensurate with the cost? The entire reason he wrote the book was to dissuade 'militarists' and stop the buildup of military potential that began with the dreadnought race and germany's more aggressive wilhelm foreign policy. The book was almost directly aimed at a german audience as a result.

Equally so, believe that nuclear retaliation we will stop a war "will only hold so until it doesn't"
In WWI every side knew how terrible, and devastating the artillery has become — to the point of making the infantry warfare obsolete, and plainly suicidal for an enemy with inferior artillery.
It's just both sides mutually believed to have a trump card, and that the one suicidal there was their enemy.
King Leopold II of Belgium got away with killing 10 million Africans right around the period mentioned (1865-1909) with barely a mention then or now. And the US has been waging war in the Middle East under one pretext or another for several decades now without being pushed into isolation.
I would encourage IceHegel to read the books more closely too.
Pinker also says repeatedly in both books that humans feel worse about the way things are than they should because our picture is anecdotal and distorted.
Maybe, but we might also dislike the present age because there are possible future worlds that appear much worse than the futures worlds imagined by past ages, even if those ages themselves were more violent/less educated/more unequal/etc. than our own.
Also, Pinker wrote a book on how the mind works, which is very very wrong (my wife, who's a psychologist absolutely hates it). She asked me to read a small article called "That's not how the mind works" by some guy at MIT to explain.
Then I've also read his book on "How to write" and as an avid reader, I'd say we'd not have had Shakespeare if we followed his advice.
And now you're telling me that his other books are also very shallow? Does he not realize it?

Seems like a solid retort, however this field is not specialty.

You may wish to read his reply to Taleb's critique of these books, where he addresses the criticism that he ignores tail risks.
