Rewind a Bit

Ponder this.

Egypt is supposed to be doing its best to stop the flow of weapons across the border at Rafah into Gaza. Egypt claims it is difficult to seal the border.

The amount and type of weaponry and ammunition smuggled is believed to be getting worse with time. There are recent reports of anti-tank and anti-aircraft missiles being transported.

Rewind the process a bit, and consider these questions:

1. From where did all this weaponry originate?
   
2. Through which sovereign country did all these anti-tank missiles and weapons travel before arriving at the border?
3. What efforts were made to stop them?
4. What efforts were made to support the transportation and by whom?
