I disagree. If this ceasefire had not happened, the US and Israel would bomb all of Iran's electricity and fuel facilities. That's what was supposed to happen today, and is what forced Iran to the negotiating table with an hour to spare. China and Pakistan told Iran to come to the table, and negotiate, because they do not want a collapsed Iran.

Without electricity, there is no modern life. There is no ability to communicate, run a financial economy, pay salaries, etc. Without fuel, there are no logistics; there is no capability to transport an army. Nor is there an ability to transport food; it would cause an enormous civilian crisis, and this would cause massive riots.

Iran would collapse, within a week. It would devolve into factions, and a civil war would start, similar to in Syria.

The US and Israel have been sitting on this card the entire time. They don't want to do it, because it would cause near permanent economic damage to Iran.

That's not at all what it says; and a higher standard of rhetoric really should be expected from comments here.
