It is fairly obvious regime change is planned for Iran. Most likely proxy forces will be used like Saudi Arabia, UAE and Israel. Now the Iranian regime is not nice, authoritarian etc. Australia being the original "metoo's", will ask " how high" when the US says jump.
My question is this; first reduce it to 2 actors Saudi Arabia Vs Iran.
Who would you support?

Personally I have no time at all for the Saud royal family and could never support that regime. This will label me a traitor in my own country. Such is life.
