A “deal” for what?
For Hizbullah it means control over Lebanon and US non-interference in a war against Israel. For their mullah masters in Iran the “big deal”, meaning accepting their nuclear program (insurance for them), putting regime change off the table, lifting the sanctions, accepting their claim to regional great power status in the neighborhood (Iraq and Afghanistan) and influence in Africa and S-America. In exchange they’ll for now refrain from attacking and promise not to use nukes. It’s an insane deal meant to cement the mullahs rule and power. That’s their chief motivation. They hoped for such a deal in 2004 already, but the Bush admin refused it.
