I want to know the answer to the following question:
In enforcing a charge of genocide, what loophole do many of the signatories possess?
All the background I'm provided with is that "In particular, some of the signatories—namely, Bahrain, Bangladesh, India, Malaysia, the Philippines, Singapore, the United States, Vietnam, Yemen, and former Yugoslavia—signed with the proviso that no claim of genocide could be brought against them at the International Court of Justice without their consent.". Is that enough to answer the question?
