See my blog in the Huffington Post U.S. Law Limits Options for Nonviolent End to Nigerian Girls Nightmare posted May 16, 2014. Here is the conclusion:
The Obama administration and Congress should make it clear that dialog is needed to free the girls of Chibok. It should actively discourage all parties from using the tragedy of the schoolgirls as a wedge for larger, long term military presence in Nigeria. And it should show its commitment to dialog by removing legal restrictions on engagement with Boko Haram that is aimed at nonviolent means of securing the girls’ release.
