Changing the name doesn't change the type of 'war' from what it was originally called, blitzkrieg. Notice it was also planned well in advance and it was started with a false-flag operation, another art form that Israel has perfected.
At some point a world at large is going to have to question the sanity of a 'Nation' whose only option to finding peace is to kill all her real and imagined enemies rather than make even one concession (while asking the 'other side' to make endless ones)
Israel has never fought anybody who has been able to defend herself effectively and her main method since 1967 has been to attack the civilian support apparatus. A first strike would only galvanize all Iranians the same way Pearl Harbor was used to get America backed by the people to get involved in WWII. If 9/11's 3,000 deaths could be justified to set off two wars in two different Nations with a slaughter of civilians that is close to 2 million then the world is not going to say the deaths of 30,000 or more is something that should not be retaliated on.
Israel has refined to perfection the one-punch war where they attack and then call a truce (once their original war plan has been exhausted). If they view Gaza as a un-ending war then they have no concept of what Iran is capable of from a purely defensive position.
Israel would have to control the air and to even get aircraft there she has to refuel, those places cannot be protected as the refueling planes are an easy target.
Iran can easily survive a first-punch and live to fight another day, Israel can't as she would wear herself out trying to protect all sides all the time.
