UN agencies, government aid programs and NGOs have consistently and willfully aided and abetted Hamas as it built its vast terror infrastructure in the Gaza Strip. They diverted aid money to Hamas to fund its terrorist activities, provided propaganda and disinformation support to Hamas in its efforts to tarnish and discredit Israel, and indoctrinated Gazan schoolchildren to hate Jews. Systematic documentation of the roles played by UN and government officials, as well as NGOs operating under the vast framework of international humanitarian aid, in enabling and cooperating with Hamas, both tacitly and actively, is vital to prevent a repetition of this abdication of responsibility and accountability.
