On this, one might point out at the creation point of the Euro to the Dollar....it roughly 1.05 Euro to the Dollar. At that point, the Bush team took the Dollar to weak levels and it became a joke in Europe just how low that they’d allow the Dollar to go, in benefit US companies.
Within the last three years, things flipped...the Euro is resting near .90 to one Dollar.
For the Trump team to suggest some imbalance...they could be correct in some marginal way...expecting the decade-long Bush gimmick of a weak Dollar to carry the trade business as being “normal”. But lets face facts....between Greece faltering, serious issues in Spain and Italy, US banks still in bad trouble, and one-star Fed policy landscape...both the Dollar and Euro are in a weak position.
Fiat currencies will always be in a weak position. One of the biggest mistakes the US made (it was a deliberate move by the Wilsonians though) was the creation of the Federal Reserve.
