I will be very quick.
Support is crucial for the minorities in Iraq. The problem is that humanitarian support alone is not enough, because they will be swept by the other forces; they have to be supported by military means as well. Without military means, without weapons in Iraq, those communities will not survive. The only humanitarian support that will be relevant will be possibly burial services.
The Kurds managed to hold ground in Iraq and defend themselves only because of the weapons. We see that in Kurdistan. We see it on a smaller scale in Kobani and other places in northern Syria. Without that, humanitarian support is totally meaningless.
