Last summer's Israel-Hezbollah conflict could be fought over time and on CNN. However bad it turned out, Israel still viably exists.
Iran's leader has made it abundantly clear that he's building a nuke to erase Israel from the map. Should that happen, Israel won't viably exist.
It's the difference between the neighbor's kid bullying your kid, vs. the neighbor publicly promising to kill you and is now setting up rifle & bipod with a clear view into your bedroom window.
Iran also promised that we were going to be non-existent. I don't see us doing too much about it.
Any thought of Iran nuking Israel is ridiculous. I would think the first reason is if Israel is nuked, the Palestinians will also be destroyed, since a nuke hitting Tel Aviv will also have a severe impact on the West Bank and Gaza.
As of yet, I don't see the Palestinians having any concerns about being wiped off the face of the earth by their sponsors.
In addition, the Jordanians, Lebanese and Syrians don't seem to be complaining about the thought that they will also lose thousands of people from radiation sickness and god knows what else.
No, Iran having a nuke just makes it easier for a conventional war because it neutralizes Israel's nuclear capabilities. And if Israel isn't willing to inflict collateral damage, then Israel will not exist, because their enemies already proven that they will attack cities.
"Get a sense of proportion."
I have a sense of proportion. If Israel isn't willing to kill the enemy 5 miles from their border, they are not going to launch a nuke and kill thousands of people to stop Iran from building a nuke. Especially if Iran puts civilians in the way?
I still contend that the only way to stop Iran is to threaten China and Europe by taking out Irans capacity to pump oil. And that can be accomplished with minimal casualties and have the most impact.
