Sanctions are also to really get your enemy to become intransigent and to start wars.
Just ask the Japanese prior to WWII how US sanctions worked.
They finally got sick and tired of them and attacked Pearl Harbor.
Sanctions are just dumb—and a million words can’t make them wise.
Do you believe Japan invaded China because China wouldn’t trade? That England started the Revolutionary War over that? That WW I or WW II was over that? That the Vietnam or Korean War was over that? That the Mexico-American War was over that? That the Cold War was over that? That the Civil War was over that?
It is daft to believe sanctions are responsible for wars. There are numerous reasons behind wars, and sanctions as a cause ranks near the bottom.
