Because they have a very deep and irrational hatred of Jews that stems directly from the way the koran talks about them.

Yea, I do wonder, why that might be? Why is a country 1500 miles away, that doesn't even share a common border, preoccupied with the destruction of Israel to the point it invested hundreds of billion of dollars in its offensive capabilities and network of proxies on every side of Israel, had a special paramilitary wing (Quds Force) for operations inside Israel, had a public clock counting down the existence of Israel and called for the destruction of Israel on each and every opportunity?

What's the obsession with the destruction of Israel? Could it be related to the fact that an Islamic Republic of (...) could not accept a Jewish rule right in the middle of the great Muslim Ummah?
