Anyone painting this in simple terms isn't paying any attention or is driving a narrative.
This engagement or war if you prefer involves the globes 3 largest nuclear powers, shit tons of proxies, the entire ME OG, Israel, and a region whose control has been fought over "globally" for well, since Alexander the Great, and regionally prior.
People often get their news from their biased Twitter content or whatever platform and tend to regurgitate whatever their teams talking heads are saying. Sadly, the ability to have logical, complex discussion just aren't very realistic because it requires looking at all sides of the issues, of which there are numerous in this instance. It also requires one to be open minded enough to be critical of one's own "team" and at times supportive of the other.
I'll use some examples on me.
I strongly believe and was in favor of ending Iranian nuclear capabilities. I am strongly in favor of the current Iranian regime being toppled. I am glad the attacks were made, I am fearful of the reprocussions. I don't like that the talk from our politicians is that it wasn't to overthrow the current regime, but I understand to say otherwise could potentially escalate this already extremely dangerous situation to a far worse level.
I don't want US troops in Iran but recognize that attacks by Iran or it's it's proxies could lead to that reality.
I would like Iranian people to he free of tyrannical rule and to find its own autonomy but realize that's mostly hopeful.
I don't have any confidence in the current US leadership to handle the situation smoothy or with tact, but acknowledge it's the hand we are dealt.
I wish this group of largely university educated middle class and intelligent posters could have a complex conversation and discuss news and developments rationally without dropping in constant political shit talking commonly found on social media. I also acknowledge that's not going to happen and it bums me out, because if this group can't there is zero hope for the US public at large to do so.
