With both Israel and Ukraine largely reliant on the US for these interceptors, decisions have to be made. 

“We still don’t know how many missiles Israel decided to engage, any number of missiles do just land in areas that aren’t going to cause much damage to human life or infrastructure… they will choose to let them pass” Mr Hickey said.

Decisions like this could help Israel conserve interceptor ammunition for further attacks on its territory.

Saturation

Again, because there are genuine concerns about the scarcity of air-defence interceptors, there are fears Iran could attempt to overwhelm Israel in any large-scale bombardment. 

“Tonight it seems that Iran launched fewer but more advanced missiles, but if this was to escalate into a conflict, this is something Israel is probably aware of,” Mr Hickey said. 

“That might be a reason not to escalate this into a full conflict.”
