Shipping insurance has risen from $15k/day to $450k/day (entire voyage) for those traveling through straights of Hormuz.

Iran's drone, and short range, capability, is not as censored as its Israeli strikes, has shown capability of breaching Gulf states with missile and AF interdiction capabilities.

Straits of Hormuz is much easier/closer target. USS Abraham Lincoln withdrew to a safer distance, after first attack on it. The insurance subsidy is both an excuse to raise them to $10M+/day for US taxpayers to subsidize, and for spectacular embarrassment of destruction of escorts and cargo.

US can't protect targets with defense pacts further away than Straits.
