Looks like being a genocidal dictator is a bit like owing millions to a bank.
Owe your bank a tenner and they'll write to you asking for the tenner back, and for an extra 20 quid for the letter.
Owe a bank millions and they'll write to you offering a bit more money.
So it's the same way with killing people.
Kill one person and when you're caught you get a spell in chokey, but kill a few thousand and the international community get together and find you a luxury pad somewhere in a nice warm place, where you can enjoy the pallets of money you shipped out ready for the inevitable day you had to leg it...
Karl Marx said "Religion is the opium of the masses", and like any drug dealer, the heads of the religions are fiercely competitive and will use their followers to enforce their territory by any means necessary.
Yes, exactly like those countries. Surely you're not so naive as to think that such changes can happen overnight? Our own democratic system took nearly four hundred years to come to full maturity after the English civil war.
