Marc,

In answer to your question:
Does that mean that US are not the only one trying to save Kagame?

Amongst the other non-permanent UNSC members today I cannot see one that would do such a thing? Although South Africa can follow a strange policy at times. The members are on:http://www.un.org/sc/members.asp
