True enough. But of course, any WMD attack by Iran and/or Iraq would be met with a retaliation by us (with hydrogen bombs) that would shake the foundations of Hell itself. It would be total and utter suicide for them.
Here is what I see...
Iraq sends two scuds at Israel with chemicals, kills a few thousand. The IDF nukes Baghdad kills millions. Then the unthinkable occurs. (Are you ready for this one?)
Saddam Hussein demands that Israel surrenders or faces countless scuds over the following days.
Sharon realizes that there is no way to defeat a mad man that cares nothing for millions of his own and surrenders rather than face more Israeli casualties.
Sharon agrees to specific terms, which includes America must withdraw from the region, leaving Israel standing alone, and Israel is de facto ruled over by Saddam.
It could happen. We are talking about Saddam here. Since you cannot find and destroy each of his scud missiles, you cannot win against him short of a massive, sudden nuclear strike all across the Iraqi frontier. Then you get into genocide, and stuff like that is very difficult to justify.
You and I agree, read Isaiah 14-19 and Jer 49-51. They descibe just that.
