Even with Putin insisting to extend the New START, Trump won't do it. He hates the black man that negotiated it, signed it and saw it come into effect. I strongly suggest Russia and the USA draw up a New START II and move forward while there is still a year until the end of New START.
The New Strategic Arms Reduction Treaty (New START) (click here) was signed April 8, 2010, in Prague by the United States and Russia and entered into force on Feb. 5, 2011.

If New Start lapses, both countries will be free to deploy more nuclear warheads and build new generations of weapons and delivery systems. While both have been steadily modernizing nuclear forces in asynchronous cycles, they were adhering to New Start limits. All bets are off without it. Russia has lately boasted of new programs such as a hypersonic glide vehicle, and the United States has confirmed deployment of a new, low-yield nuclear warhead, the W76-2, on a submarine-based ballistic missile. These developments are but a hint of what will come with unrestrained nuclear competition....
