Reciprocity. Two-way street. I tariff the he** outta you and you tariff the he** outta me. Is there any limit to the amount you can tariff?

We tariff  25%. We get Tariffed back 50%. I mean back and forth it goes. Where it will stop does anybody know? Stockmarkets worldwide crash all because a petulant doofus in America was angry and wanted to fight so he started a trade war? He got bored. He was unhappy. So he figured out how to get attention. SIGH.
