If Trump was a Japanese warrior would he have to commit harikari ?

For years Trump has been claiming that he will make America great again with tariffs. But since he has been in office all he has done is show the world that he is a blowhard. He has put ridiculous high tariffs on goods – only to lower the tariffs or pause them a week or so later. He has lost face in the eyes of the world and Japanese warriors have commit harikari for less. Cheers!
