I can visualise Putin rubbing his hands calculating how many assets are being tied up and how many munitions are being expended on Iran and not on Russian forces in Ukraine.
This war will get messy very quickly and I predict when that happens American forces will go home causing a vacuum to be filled by terrorism. The alternative are boots on the ground, Trumps very own Vietnam.
Libya, Somalia, Iraq, Afghanistan all good role models for Iran.
Doesn't bode well for the future.
