In 2013 the USA donated 300 million dollars towards UNRWA, an organization that is aiding and complicit to the actions of a terrorist organization, Hamas.
In the past 2 weeks, rockets have been discovered being stored in 3 separate schools, and then turned over to Hamas, which used them for war crimes.
UNRWA has changed the definition of a refugee, going against the UNHCR. They also continuously allow gunmen to fire from inside school properties, and surrounding school properties. This not only supports terrorists (Hamas) it endangers those it is supposed to protect.
By aiding Hamas they are helping in the murder of thousands of individuals, including the recent kidnapping and murder of US citizen Naftali Frankel.
