Hamas in Gaza is an enemy of Israel and is attracting on itself an Old Testament curse which will also apply to Iran, or any other force which tries to attack Israel.
Zechariah 12
2 Behold, I will make Jerusalem a cup of trembling unto all the people round about, when they shall be in the siege both against Judah and against Jerusalem.
3 And in that day will I make Jerusalem a burdensome stone for all people: all that burden themselves with it shall be cut in pieces, though all the people of the earth be gathered together against it.
