Gaza is surrounded by Israeli forces who control the access to the land strip, the airspace the sea , the borders, the population registry and Israeli army is free to intervene anytime
Which does not contradict my statement that Israel is not present in Gaza, and last time Israel intervened in Gaza Hamas killed quite a few soldiers, so they are clearly NOT free to intervene there anytime.
So why there are Israeli army checkpoints everywhere in the west bank?
We can discuss that once you acknowledge that the Palestinian Authority has a security force and is responsible for law and order in the areas it controls.
