Hi Kumar If we go by karma, then the saudi arabia should be eradicated for what it has done in terms of support to many terrorist groups, for killing many sufi saints etc. Its also the same with many other islamic countries like afghanistan (anyway its being desroyed in the fight) who invaded india and used force for killing & conversions etc.
For that matter, its also true with US for having killed many native indians there...
But the law is very subtle and we will never be able to understand it, unless we are a God realized being...
