Somalia starves, millions are at risk of starving to death yet Al Shabaab still refuse to recognise the gravity of the situation, they continue their fighting and block aid agencies from entering Somalia. Millions will die if nothing is done, Al Shabaab drop the rifle and help your people. w'Salaam ~ Peace.
This is the ONLY case I could say a international forced intervention (to take down Al Shabaab) would actually be recommended. But any intervention only happens when the other countries have interest in it. Sadly, most countries, even the rich ones, are not concerned with helpin' others just out of charity...
