Trump: trade wars are good and easy to win

Amid growing concerns over a global trade war, the US President Donald Trump tweets on today's hot topic and said:

When a country (USA) is losing many billions of dollars on trade with virtually every country it does business with, trade wars are good, and easy to win. Example, when we are down $100 billion with a certain country and they get cute, don’t trade anymore-we win big. It’s easy!
