Well, Nintendo increased the sale price on NS2 in Europe and Australia to compensate for the tariffs in the US, so they could keep the end-user price down for US consumers even with tariffs. This effectively shifted the cost of the tariffs to European and Australian consumers, which is why I have sworn off Nintendo for good.
I get that Nintendo's policy is fucking you and the good friends in Europe and Australia, but it still makes the title misleading. My (Japanese) government didn't impose the tariff on Nintendo products — the Americans' did.
In some cases 'they do' (they don't) as the tariffs imposed may well be enough to stop people buying X at 150-200% of normal price, if selling X to US was a big enough chunk of BizY's business, then that does impact the target country, not just US citizens.
In all cases US citizens hurt, but in a few the target country does too.
