Moral Duty to intervene?

Given the disaster in Burma and that Government's indifference to the pain of the people - the question to be asked is: should other nations have the right to intervene in a clear humanitarian crisis where the local government is indifferent? My view is yes - Burma should have been invaded and the regime changed a long time ago - much before Iraq or Afghanistan or the nations in South America.

An article in the Economist questions the legality of a unilateral intervention by the UN in Burma

Responsibility to protect is not yet dead, but it is fragile.
Supporters point to the power-sharing deal that stopped Kenya's civil
war in February as the concept's first success. The fact that the UN, in principle, retains the right to impose its will by force may have made it easier for the world body to broker a settlement.

Perhaps. But the idea will need some clearer successes than that if
it is going to survive. And Myanmar, apparently, is not going to be one
of them.
