KungFuGuy!, your tactics led to the death of many Jedi that day.
Padme lasted just fine without Anakin defending her. She was able to fight off the monster that attacked her, and she was smart enough to take cover. Anakin, for your information, was too busy defending HIMSELF.
In Episode I, you will recall that the Gungans were roundly defeated in close combat by the battle droids. You don't remember this, but the droids routed the Gungans by blowing up the force field in your close quarters. Because of this, countless Gungans died AND they lost the battle. In short, your strategy failed miserably.
Your logic about the clone army is flawed, KungFuGuy! By your estimation, you'd take an army of clones over an army of Jedi. Besides, taking out sentries didn't stop the Jedi from getting shot up or from being rounded up at the end.
Throughout history, air forces have been employed to soften up ground positions BEFORE ground troops are sent in. We did that in the Gulf War and in Afghanistan. By your estimation, we'd send in ground troops to "take out sentries" and "create surprise". And the result would be the same as in "Episode II": a high death toll of American soldiers. Is that what you want, KungFuGuy?
I'll say this, KungFuGuy! If I were a Jedi or Gulf War soldier, I'd never fight for you. That's because you'd send me to my death via close quarter combat.
