This is an interesting, albeit quite transparent, move.  It is a well established fact that Trump and Putin are pretty good buddies now.  As such, the game of mutual back scratching has already begun.  Putin states that he wants to strengthen Russia's nukes.  That gives him political capitol and a reason to spend money on weapons.  Trump, of course, says two can play at that game.  Nukes are money.  There will be lots and lots of money given to contractors to upgrade and/or improve our nuclear arsenal.  Russia will likewise enjoy the boon of weapons development and the economic benefits of such.  It's a win-win, if your last name is Putin or Trump.
