I don't think this is what you think it is...

It looks like it is laying groundwork to prosecute individuals that the US determines to be guilty of genocide and or war crimes. 
This section seems to be the guts of Bill. 

(2) An assessment of the feasibility and advisability of prosecuting individuals for whom credible evidence exists of having committed acts of genocide, crimes against humanity, or war crimes in Iraq since January 2014 or Syria since March 2011 in domestic courts etc...criminal investigations of such individuals, and to effectively collect and preserve evidence, and preserve the chain of evidence, for prosecution.

And it specifically states that NO additional funding is authorized for the implementation of the Bill.  So... more of nothing new except a press conference on the White House Lawn?

The bill is about prosecution of suspects of genocide and to circumvent international tribunals.

Is the US wanting to name who is a refugee and circumvent the UN too?
