U.S. invading Iranian airspace is not as benign as you are pretending especially given it is not an isolated incident. It is one thing to have the neighborhood peeping tom looking in your window, another thing to have a serial killer rapist snooping inside your house. The U.S. government has aggressively worked to overthrow the Iranian government by setting U.S. public opinion against the Iranian government for possible military action. The U.S. has also installed sanctions, the 2007 congress funding of covert operations inside Iran, Iranian scientist assassinations, and the recent dubious Saudi assassination plot.
