As if the lingering prospect of a new attack on Iran is not dangerous enough, the Trump administration is toying with a greater threat to global security.
With Thursday’s expiration of the New START treaty, the US and Russia no longer have any legal constraints on their arsenals of nuclear weapons. President Trump let the treaty collapse rather than accept a Kremlin offer to extend for one year, the maximum possible. This removes the last formal constraint on a renewed arms race between two states that already can destroy the world many times over.
There are unconfirmed reports that the two sides have reached an informal understanding to observe the treaty’s terms for at least six months. And, in a rare sign of progress, Moscow and Washington have announced a resumption of high-level military-to-military dialogue. The Biden administration suspended those contacts in late 2021 as Russia built up its forces on Ukraine’s borders.
Yet the news is far from reassuring.
