> If we could snap our fingers and domestically produce most or all of our own products, would you not prefer that?
I'm not the person you asked, but I would definitely not prefer that. Trade & economic dependencies prevent wars. Wars are really, really bad things.
Economic dependencies also start wars. Even if trade exists, sometimes they don't like the terms.
We've had plenty of wars since globalization came in post-WWII though. Its impossible to know what wars would have happened without it, and how much war may have been prevented due to trade rather than the threat of nuclear war, for example.
