War is aggression, often with the use of physical violence to conquer land, people, and power. Trade wars, though not quite as bad, also are aggressive in nature. Where two or more private parties want to transact freely, aggressive governments step in the way and prevent trade from happening with the threat of force.
In 2018, most of the mainstream media and the establishment powers blame President Donald Trump and his administration for starting a trade war, which—like real wars—can only produce losers on both sides. “How Much Damage Will Trump’s Trade War Do?” read a headline in The Atlantic, and countless other articles and official statements say similar things.
