You really can't be that uninformed? Seriously, are you?I will explain thing’s simply and use small words to help you understand the Adult things we are talking about:
The USA funding Ukraine in their fight against Russia is helping destroy our Mortal Enemy
The USA has long wanted action against Iran but due to possible fallout from the other Arab nations.
The USA would absolutely LOVE seeing g Iran get involved in this war so Israel could wipe them out using weapons the USA sold Israel. Hell this would be the biggest double win for the US in history.
Carry on Old Boy. I can find some pics to help you understand better if you need
The Iranians are Persians, not Arabs. They are Shia, the center of the Shiite Muslim world, and opposed to the Arab Sunnis. However there are Arab Shia also and Iran isn't above aiding Sunni terrorists. The Sunni leadership of Saudi Arabia and other Arab oil states greatly fear Iran and have aligned with the U.S. and are even making nice with Israel. But don't think they're great admirers of the U.S. They love our money but not our culture.
Anything else you would like explained to you feel free to ask and I'll do my best to point you in the right direction. Maybe start without how wrong you are about our orange leader...
