Just two days ago, Jan. 24, Sen. Edward Markey (D-Mass.) introduced a Senate Bill (S-200) to do just that!
"RESTRICTING FIRST USE OF NUCLEAR WEAPONS ACT 2017".
The same bill (HR-699)was introduced in the House of Reps by Rep. Ted Lieu (D-CA).
The bills would prohibit POTUS from launching a world-ending Nuclear First Strike without a Congressional Declaration of War - as required by our US Constitution.
This legislation is introduced while the Bulletin of Atomic scientists has reset the "Doomsday Clock" to two and a half minutes until Midnight! The closest the clock's hands have been to Midnight since 1953 and the advent of the world's first hydrogen/thermonuclear bombs.

The legislation has the strong support of former Sec of Defense William J Perry who stated that launching a First Strike "would likely bring about the end of civilization", "a decision that momentous... should have the checks and balances called for by the US Constitution."
If we care about our world, our lives and future and the lives and futures of our children and grandchildren - we must support this Bill. It is a Moral Imperative.
END THIS ONE MAN NUCLEAR MONARCHY NOW
