I agree that at the present time it seems almost inconceivable that the Zionist regime in Israel would ever come to an end (through an internal process).

However, it wasn't very long ago that it seemed inconceivable that the Soviet government would ever come to an end through an internal process.

But they did! And Russia was not wiped off the map.

Every form of government, every regime, someday passes from the page of time, and then it's gone. If you wait long enough (as a disembodied spirit watching the world), you will see that this is true.

The Ayatollah was saying that the Zionists would be gone one day (as something he would like to see). I'm sure they will...but that day may be a century off...or five centuries in the future...or more than that. It may be in 1,000 years. Who can say?

Does the USA not frequently express the fervent hope and desire for the present regime of Iran to be gone? It does! How is that any different from the Iranians hoping that the present Zionist regime will one day be gone? Anyone can hope that a present "enemy" will not be around at some point. That does not equal a threat of launching open war, nor are the Iranians in any kind of position to do so.

Were they to build a few A-bombs of their own, they would still be in no position to do so, but they would have a credible deterrent against being attacked by tremendously superior American and Israeli nuclear firepower.
