This doctor's frustration is understandable, but there are so many wars going on in the world at the moment ... so many in the Middle East and parts of Africa.  No matter how many times other nations respond, the wars continue, and the flood of refugees grows every year.

The UNHCR (developed in 1951)  reported 45.2-million refugees between 2012 and 2013, but that figure was revised upward to 65-million this year. Over-population is obviously a big factor.  The five main trouble spots are Afghanistan, Somalia, Iraq, Syria, and Sudan.

As Jeffrey Simpson once commented, this war is a nasty modern manifestation of an old fight between Sunnis and Shiites, and between different schools of Sunni Islam.  In this struggle, the West is hard-pressed to support one side without inflaming the other(s).  This war has its roots in fanaticism & fundamentalism ... and over-population.  How can 'the world' (meaning Western nations usually) solve that?
