If you examine it from a Biblical world view: Israel was intended to be God's chosen people through which the Messiah was to come. The Old Testament is replete with stories whereby they endured horrific wars & exile but God miraculously preserved the Messianic bloodline many times and viola' Jesus the Christ was born - Hence the New testament.
Though it was God's original plan being worked through human elements, when the Jewish Leaders demanded Jesus's death and swore 'His blood be on us and our children' it was the dumbest thing in history imho; this invoked the curse whereby not only has Satan's minions has targeted Israel for destruction because of Messiah, but those fateful words did more harm as well.
My 2 cents...

Well, yes, it was dumb thing to say, but it is not the cause of the world's hatred of Israel.
Israel was called as God's chosen people. Through all the sins, apostasy, rebellion, blunders and sheer stupidity committed by Israel, they remain God's chosen. The natural man hates God and all things Godly. The intensity of the world's hatred of Israel is a barometer by which we can sense how much of the world is "natural" and how much of the world is moved by the promptings of the spirit.
"His blood be on us and our children"
They swore that and God gave them what they asked for. Jerusalem, the Temple, and most all of the Jewish inhabitants of Jerusalem were destroyed by the Roman army in A.D. 70.
That doesn't mean the oath applies to all of their descendents 2,000 years later as well.
Amen. In addition to a lot of the other answers on this forum, people are forgetting that this is truly a spiritual battle.
