That's because you apply your standard selectively. The notion that all Western governments join hands and denounce humanitarian disasters whenever they appear is puerile; the West is either directly responsible for or financially supportive of some of the worst atrocities of modern times.
Without a list, I won't guess what you mean, but "The West" has also been responsible for, or financially supportive of some of the most humane actions of modern times.
Frankly, I'm not familiar with how whatever we may define as "Islam" has filled in this side of the balance sheet.....unless Saudi Arabia is sending shipments of rice to Chad, and UN troop to Bosnia?
