It's pretty nuts to be that aggressive towards Iran, when we're already in how many wars? Those wars have cost us so much money (in the trillions, and note who's getting rich off of it) and lives (thousands of Americans and hundreds of thousands of civilians in Iraq, Afghanistan, Syria, etc). The last poll on the subject of being millitaristic towards Iran had like 16% favorability, not that Washington much cares what we think about things anymore. Getting back to Iran... so we kill that general, and then turn around and say if Iran retaliates we're going to retaliate back, perhaps in a disproportinate way. You think they are just going to take it without responding? And we're the victims in all this apparently. Just wow.
If you ever decide to pay attention to politics, be super wary of any mainstream media. You have to look into who they are funded by and why they might say certain things, and talk or not talk about certain topics. Your best bet at getting any kind of facts and who admit to bias upfront is online media, like some YT shows, and some international media.
