The Arab countries Iran is attacking are all part of the Israel/US effort to oppress Iran. And USA has bases there and is attacking from those countries.USA also has intelligence offices in those countries, that Iran have hit, and was acused of hitting a civilian target because it was a hotel. When in reality US intelligence was hiding behind civilians.The Arab countries are also a key part of the Petrodollar, that is a HUGE factor in why USA is waging war against Iran in an attempt to control the area.
Actually this war could change the political picture in the world as we know it, if Iran succeeds with their strategy, and the petrodollar collapses. So Iran was in fact at war with all those countries by proxy when USA attacked.
Imagine the number of attacks the world could "morally" do on USA, if preemptive strikes were considered self defense.How many countries even allies has Trump threatened? Panama, Cuba, Denmark/Greenland, Canada. Are some that I remember for sure. Besides actually attacking Venezuela and now Iran.All these countries could legally perform strikes against USA by the logic of the current American Government. And then they wonder why so many people hate USA.
