Despite then-Secretary of State John Kerry's declaration one year ago that ISIS's actions in Iraq and Syria amounted to genocide -- and unanimous votes in the House and Senate asking Kerry to declare genocide against minority Christian, Yazidi and Shia Muslim groups in the region -- advocates at a first anniversary ceremony said they want more from the US government than what's been done to date.

While the genocide declaration is in itself rare, "there was more politics to the issue of genocide which I ever thought there could be," said Catholic University of America law professor Robert Destro at a March 16 event at the US Capitol Visitor Center sponsored by In Defense of Christians, an advocacy group for Middle East Christians.
