The New START treaty, the last remaining agreement constraining Russian and US nuclear weapons, is due to lapse on February 4.
There are no negotiations to extend the terms of the treaty, either. As US President Donald Trump said dismissively in a recent interview, “if it expires, it expires”.
The importance of the New START treaty is hard to overstate. As other nuclear treaties have been abrogated in recent years, this was the only deal left with notification, inspection, verification and treaty compliance mechanisms between Russia and the US. Between them, they possess 87% of the world’s nuclear weapons.
