Yes. It's a very strange and basically un-contested idea that trade integration discourages war. If that was true then civil wars would be the rarest form of war, but the only type of war going on in the world today is civil war. And if you look through the 20th century, then other than the World Wars, most conflict was civil in nature. You can't get more integrated than a countries internal trade. So this idea that trade deals make war hard doesn't seem empirically supportable.
