The security logic was just as you say, but it never seemed very compatible with the facts of history (https://en.wikipedia.org/wiki/Opium_Wars), as there have been plenty of wars started _because_ of global trade. But regardless, current events ought to put the final nail in the coffin of this wishful-thinking (but commonly held) piece of logic. Regardless of whether or not it _should_ make countries less likely to go to war, it doesn't in fact actually seem to.
