The world should be helping Syrian refugees in any way possible, and helping to facilitate Syrian war victims in getting help inside of Syria as well. Although it is too dangerous for humanitarian agencies to work directly in Syria, groups in Syria providing medical care should be supported, and there should be a greater focus on accepting refugees that escape.
Yes, humanitarian agencies need to do more to help refugees and others affected by wars as well as natural disasters. But humanitarian agencies shouldn't shoulder the responsibility alone. They need support from governments and financiers who can help them reach the people around the world who need help the most.
Humanitarian agencies are doing all they can, especially in worn-tron countries such as Syria. It is very difficult to get supplies into these countries given the ongoing conflict. These people are already putting themselves in harms way in order to help people. The agencies are also operating with a shoe string budget.
These kinds of injuries keep happening over and over due to the interfering military presence in these regions of the world. Troops are kept here due to a corrupt and bogus "war on terror" that creates the problem and tries to sell the public on how necessary it is for safety.
