美国总统特朗普通过书信的方式，在7月8日告知对日"对等关税"税率为25%，但到8月1日正式启动前， 日本依然有谈判的机会。 对于原本24%的税率，通过三个月来经济再生担当大臣赤泽亮正七次赴美、首相石破茂亲自与特朗普交 涉，不仅没有降低，反而提升了一个点……对这一新税率，石破表示了"遗憾"，做出让对策本部"继续 交涉"的指示。但舆论普遍认为，让美国改变税率已相当艰难。 日本自上个世纪六十年代开始，基本每十年便会和美国发生一场贸易战。攻防的内容从纺织品变为钢铁 后，进入到了家电、半导体阶段，最后汽车成为了对美出口赚取大量盈余的大宗产品。日本熟悉美国的 套路，总能看似败下阵来、但实际上只是换了攻防内容，对美出口保持长期盈利的态势。谈判上妥协， 让贸易得到实惠，只要日本能够从美国获利，舆论、外交上的败退对日本来说不是多大的事。 但是，这次不一样。 汽车等产品再能盈利，想获得25%以上的利润以便对冲25%的税率，并非易事。让日元汇率下调逾25% ——换句话说，将目前的1美元兑换146日元，下调到182日元以上——在美国想让美元汇率贬值的时 候，恐怕也不容易。 于是，有了日本舆论对特朗普关税的愤怒，有了石破罕见地向美国表 ...
