Bahrain: Why is al maliki of iraq suddenly worried about the shiites in bahrain?

when his gang of murderous shiites invites the USA to kill sunnis and then again invites the iranians to oust the americans and help keep shiites dominate iraq by torturing sunnis, where was his human rights preaching then?---When iran was killing iranian protestors by the hundreds and sunnis in iraq, he was very quiet! when americans were killing sunnis in west baghdad he was also very very quiet!
