This is usually because of attacks against her people and borders. The fact is that Israel wouldn't have bombed all of those innocent Lebanese and their country had it not been for the actions of the rogue element, Hizb'allah!
At least you admit that Israel murdered innocent Lebanese. At least you don't try pretend there were "human shields" or some such nonsense. The fact is that Israel murdered 1000 innocent Lebanese civilians, one-third of whom were children, and nearly all of whom never even supported (and likely opposed) Hezbollah. And there is no justification. Hezbollah's actions cannot justify Israel's because Israel was bombing Non-Hezbollah Lebanese -- in essence, Israel was bombing Hezbollah's internal rivals for power.
Israel does not have to join the NPT, nor are they required to disclose their arsenal. The world can wonder all it wants, as that is its right, but it doesn't change the fact that Israel is under no obligation to satiate their wondering.
Not to disclose nukes means that the nuclear power is a rogue nation. The nature of nuclear weapons requires that they be disclosed and regulated, and no nation should see itself as above that. And if Israel does not want to join the treaty, then Israel cannot complain about Iran's seeking nuclear weapons. And, ironicially, Iran is a member of the treaty.
fact is that Israel is believed to have nukes, but in the 30 years she has had them, has not used them ONCE! So the very notion that MAD is needed as a counterbalance is obviously lacking.
Actually, if the last 30 years has shown anything, it has been a severe imbalance and instability in the Middle East. War after war and invasion after invasion. That Israel has not used nukes does not disprove mutually assured destruction. The fact that Israel invades other nations at will (or did so until last month), proves that a counterbalancing deterrent would make the region more stable.
As far as racist views of Iranians, they are very commonplace, and media such as CNN and Fox News exhibit a hate-filled, xenophobic, racist view point on a daily basis. And the notion that Iranians are subhumans waiting for nothing but to launch a weapon as soon as they get their hands on it requires a racist view point. Since these media outlets feed the Neocon "War on Terror," it is only logical that racism and hate drives the war, and this racist viewpoint is necessary for the Neocons to launch a war on Iran.
