I do not see how most production can ever be restored to US manufacture. It will simply not be competitive. China has built an entire economy based on its natural advantages and state led strategy to win the trade war and they have won. USA cannot compete on most supply chains. All Trumps tariffs might at best achieve is a short term reduction in the (trade and fiscal) deficits by reducing US consumption and subsidizing inefficient US based alternatives. This is not going to make America Great Again. This is the policy of a president dealing with an empire in decline...and a population who still cannot accept that reality.
