I take it that the blockade has meant that there are no compasses in Gaza? they kind of lost their sense of direction if they attacked Egypt instead of Israel.
No Don.
The plan was to use captured Egyptian armoured vehicles to launch an attack into Israel.
They probably did not expect the Egyptian soldiers to resist.
By the end of that fight the IDF were ready for them.

A claim for which we have no other evidence than the word of the government which ordered the incursion.

Your prejudice and bigotry makes you just "know" it is a lie.
I believe it.
So does the whole world except you Don.
Or, can you find one other source or person in the all creation who shares your ridiculous blindness to reality?
