Where Left and Right agree
Left and right largely agree on this one.
- What both sides accept
- Both demand the Gulf escalation be justified before it widens, because $90 Brent, 15-year-high yields and a near-certain Fed hike are already pricing the cost.
- Where Left and Right differ in emphasis
- Both want the war justified before it extends; one because households absorb it in fuel, rents and debt, the other because markets reprice national borrowing costs.
How left and right read it
The bill for escalation in the Gulf is already being handed to households: the strike on Lark Island helped push Brent back above $90, and because energy costs feed straight into inflation, money markets now treat a Fed rate increase as near-certain after Warsh signaled more tightening. Rents, debt, fuel. Who is asked to justify a wider war before working people pay for it in borrowing costs?
An open-ended commitment in the Gulf has to justify itself on the same ledger as everything else we spend, and the price signal is already in: Brent back above $90 after the strike on Lark Island, euro zone yields at 15-year highs, the 10-year near 4.76%. That is the market repricing our own borrowing costs. Warsh's warning at Jackson Hole, and the near-certain rate increase now priced in, is the discipline no war plan escapes. Prove the objective before extending the fight.
