The US imposes draconian sanctions on Iran. Iran starts a modest counteroffensive. Sanctions persist. How is that a climbdown?
The real question is, as Iran increases the tension themselves, which way the situation will turn: sanctions which remain on course and strangle Iran, actual war or relief of sanctions. Only the last option is against the wishes of Israel.
A lot of people want war. A lot of pundits who have been selected for their aggressiveness for commercial reasons. A lot of loony generals who are needed in peacetime to build a case for investing in weapons. A lot of politicians who benefit from warmongering. It’s a warmongering country.
Promoting warmongers doesn’t always mean you’re in favor of war. it can mean that you just want to push things towards more conflict but short of war – until you miscalculate. Does Bolton want war? Yes. For him peace is just people fooling themselves that no war is going on. Does Adelson prefer war over sanctions? I don’t know but plausible. The Israel lobby is not the same as Israel. Does Netanyahu want war? That’s less likely.
There’s also a lot of powerful people who don’t want war with Iran, including in the Pentagon. As long as Iran is under sanctions they can accept the situation, but if Iran starts upsetting the world they will weigh in more. Therefore, Iran decides to become a nuisance.
