The dollar/euro market is very balanced ...the problem is that Germany plays dirty disrespecting the other EU countries on trade and that is why Trump wants tariffs on the European imports.
Brexit is necessary to allow UK to exit the EU and counterbalance Germany from the outside
Trump wants tariffs because he wants americans to buy american goods
The UK is s failing country. Outside the EU it will collapse.
America is not likely to ditch a market of 700 million potential buyers on favour of just 65 million with little free cash to spend
