Iran is stuck in a complicated situation, Usa is bombing Iran without any consequences, it is using bases and airspace in Saudia, Qatar, Uae, Bahrain, Kuwait, who are Usa biggest allies and backers. If Iran attacks and harms arab countries it will end up being Arab Iranian war, If Iran stays quiet they will slowly be destroyed, Iran is unable to retaliate against the Usa, and can hardly harm Israel. What are they supposed to do without a cutting edge airforce which can stop Usa bombing or Nukes which guranteed Iranian security.
