New Start expires on Thursday. That leaves no limits on US and Russian nuclear arsenals

Let’s be honest: America needs another nuclear weapon about as much as Donald Trump deserves a Nobel peace prize.

Yet on Thursday, the last remaining nuclear arms control treaty between the U S and Russia will expire. When the New Strategic Arms Reduction Treaty – New Start – goes away, there will be no limits on US and Russian nuclear arsenals for the first time in more than 50 years.

That is very bad news.

Agreements like New Start helped end the cold war nuclear arms race. Many Americans are too young to remember that era. If you missed it the first time, I have news for you: it’s back.
