Of course Israel supports the US. Otherwise, Bush might stop sending all those nice shiny helicopters and bombs.
And you're missing the point- it's not an argument about whether Saddam has MDWs or not, it's an argument about whether that's reason enough to pitch into an opportunistic war of aggression that threatens to utterly destroy several regimes, not just Saddam's, bring the terrorist thing to whole new heights, alienate the US from the entire rest of the planet (except Israel and Tony Blair- note I don't say Britain), and otherwise just **** us over nicely. Personally, I'm inclined to say that a few anthrax bombs don't come even close to being a reasonable reason to wage a war (****, the US has tons of them, and can't even keep tabs on the ones we have. The old Soviet states have stuff so nasty it makes smallpox sound like a trip to the circus. Korea and China are outright threats to the US, and have enough weaponry to kill millions of people.)- which would mean that Bush has other reasons, ones which he couldn't exactly admit to if he wanted support.
In other words, it's like a cop shooting somebody for a parking violation. When everyone's feeling kind of edgy about that particular cop, can't drive for ****, and is very heavily armed.
And tactics are the job of generals, Bob, not the President. He doesn't bother with things like covering flanks or securing cities. Which will be fortunate if we get into a war, because I can guarantee from the evidence that Bush has all the strategic savvy of a rubber duck. Same for the scorched-earth policy, though that was neither stupid nor insane- it severely demoralized the UN forces, symbolically gave the old Bush the finger, and made sure that Kuwait would be sorry it made a noise about being invaded. The SCUD was largely a political gesture, and at the time a relatively safe one, since Israel couldn't have gotten away with nuking Iraq at that point.
Your equating US-bashing in a notoriously anti-American region with stupidity or insanity calls into question your understanding of the fact that not every place is like Illinois, or that there may be other concerns for a Middle Eastern dictator than appeasing the US. I don't think I'll bother explain how politics works to you, but I will note that without his constant vilification of the US, Saddam would almost certainly have died a long time ago at the hand of one insurgent/general or another.
