That shortage of medicine is primarily caused by Hamas grabbing it every time a relief agency brings some in.
Which means ... there is NO shortage in Gaza ... Move 'em out, IDF ... Let's Roll!
HAMAS also refuses to allow the wounded to leave for Egypt to get medical treatment. Probably because they:
1) Won’t be allowed back into the Gaza Strip until after the conflict.
-and-
2) Can’t be used as propaganda in the Western press if they die.
