It’s suggested that the term “Achilles’ heel”, meaning a seemingly insignificant point of fatal weakness, comes from exactly your observation of the Dendra Panoply, an armour of exactly the same period as Achilles and the Trojan War.

Yeah, but let’s consider what happens:

• Tariff applied
• Prices go up
• Supermarket trolleyfull becomes more expensive
• People have less money to buy other things
• Companies sell less
• Company profits fall
• Stock valuation drops
• GDP falls

That’s why the Dow Jones and S&P are lower - this shrinks company profits and US GDP.
