Also, a question. For the near future with Is/Us v Iran any hostilities are likely to be of the missile/drone/bombing variety, right?

Agree. An armchair general sitting next to me tells me that there are logistical problems in Izzies bombing most targets in Iran i.e. refuelling of their jets. Thus bombing is very unlikely imo. Apart from that I would be careful about S400s just delivered to Iran by RF. I think Izzies have been check-mated in this instance ..
