Nah dude. You said Iran can't because they "want to exterminate a race," they obviously don't, because they have the second largest Jewish population in the region after Israel itself and any Jew who thought they were going to be murdered could flee to Israel and be given a home.
The Amelekites question is pertinent. Netanyahu and other Israeli officials have called the Gazan Palestinians "amalekites," a people group that the Hebrews were supposed to slaughter man, woman and child, destroy their livestock and possessions. The modern state of Israel has always presented itself as a second incarnation of the post-exodus Israelites, and now they are literally driving bulldozers over entire cities and settlements.
In other words, both countries have expressed genocidal intent. But only one is actually acting on it. Neither should have nukes, but the one that is actively killing women and children actually does have nukes, the other is led by a theocrat who claims WMD are against their religion.
I'm saying we should keep our nose out of it and not tip the scale towards one, because both aren't worth being "on the side" of.
