From a pragmatic and cost effective basis, this is a terrible policy the US is following here. This is a tiny rural island with a few people living there which just happens to need mail routed through the US very briefly even mail from Canada to Canada. There is no history of mail abuse or criminal operations taking advantage of this system. So while the US may technically claim the right to search every letter under this unique situation, it's a massive waste of time, money and US taxpayer resources to to this, money that should instead be spent on legitimate issues where there is a real threat. In short, these searches subvert US security by diverting resources away from where they are needed. Probably some petty tyrant on a power trip started this whole debacle. Whoever that is needs to be stomped on by their supervisory agency for wasting resources in the personal pursuit of puerile ego trips.
