ummm.... how many Americans are dead?
You do also know an Australian is dead?
How many US hostages are there?
You think the US is not going to try to get its people out?
Second to that the US is a non-NATO ally with Israel.
If Australia was attacked are you saying you would like our ally to not move their ships into the area?
It will be Iran's choice if they want to step in from here.
