Muslims so far have only teached themselves a lesson. They have united several times in the past and only got beat up.
With 100+ nukes, Israel can teach the Muslim world a pretty good lesson. Mecca, Medina, entire Iran, etc. are all within range of Jericho missiles. The entire cultural bases of the Muslim religion could be wiped out in few minutes, along with a large amount of the Muslim population. Those who'll survive, mutated, will probably return to their nomadic roots. I don't think that's a too good of an outcome for your "Umma".
So please, act reasonably. Despite your roots, try to understand why Israel can not and will not tolerate any further aggression by the Hizbullah, and why people like yourself - enlightened enough to express their opinions here - should want to see the Hizbullah destroyed for the peace of future generations. I'm sure that were the Arab world less devoted to "teaching Israel a lesson" and focusing on its own problems, Israel's GDP wouldn't be that of Egypt, Syria, Jordan and Lebanon - combined (or something rediculous like that).
