The ICJ have considered the evidence and come to the conclusion of Apartheid in the WB.
I have posted links for both of these.
You can equally argue that Likud party policy have strengthened the hand of Hamas by not engaging in a 2 ss with good faith. Netanyahu has been open about dividing and conquering Palestinian leadership.
