Azizjan, stop being a simpleton for one second and gain some insight into how the US economy works.
The US economy was based on protectionism and heavy tariffs on foreign goods for 250 years before the rest of the world destroyed itself in 2 World Wars and stopped producing anything worthy of tariffs. Then around 1945, in good faith and perhaps just to bring some prosperity to war-torn Europe, America started to open things up towards a free-market economy. This worked fantastically for the rest of the world and put a lot of strain on American manufacturing. It virtually brought growth to a halt in America for decades while countries like Germany, France, China, Japan and England dug themselves out of massive holes and prospered. This came directly at the expense of every American citizen without access to global trade.
Funny thing is, Trump is not even a true protectionist. He's actually an advocate of true free-trade, but not a single one of those so called "allies" is willing to admit how sneaky and unfair they've been in return. If they continue their sneaky ways (which I strongly believe they will), in a few elections a true protectionist will get elected in the US and that's when you'll see some true bullying. That's when instead of tariffs, bombs and missiles will determine the outcome of trade wars.
