Sure, let Israel retaliate while we've got the entire Desert Storm armada of troops and tanks deployed along the Iraqi border.
You doubt it would have happened? Go back and take a look at how many times Israel has conducted retaliatory or pre-emptive air strikes.
If one...just one...of those missiles that hit Tel-Aviv had had a whiff of chemical weapons on it, all bets were off. It was a very real concern at the time and it was a valid concern.
After all, we gave Saddam chemical weapons to fight the Iranians. He had them. He'd used them before on the Kurds and Iranians.
To kick back now, in hindsight and say there was never a danger that Israel would have retaliated is Monday Morning Quarterbacking at its finest.
