Long suspect the whole thing was planned events since the helio incident.
Internal Hardliners and Hezbollah were sacrificed, to avoid a direct war with Israel.
These rockets point toward Israel at Lebanon, Iran doesn't want to be held responsible.
Now,obviously, Israel won't let Iran off the hoke easily. Ayatollah is quite unpopular as I heard. Can Iran avoid regime change and hold its own?
This is not rare even in China's recent history. Soviet struck a deal with Japan, Northeast resistance collapsed, remainings withdrew to Soviet (including Kim).
