Nah i dont think its a good idea. A paramilitary institution cannot accept donations (atleast this is the case in India,maybe same for US?). JTF needs funds for its movement right now. IDF will be JTF's military force in future God willing!
right wing Hindu organisations (RSS,VHP,Bajrang Dal) in India with slight militant leaning have been barred from receiving donations and foreign funds by our socialist government, while Islamic mosques and Missionary churches receive heavy foreign funding.
