The biggest death toll in the Iraq war didn't come from the US explicitly bombing civilians, it came from the US destroying the infrastructure and military of Iraq, leading to a failed state which melted the economy, led millions to destitute poverty, and created the conditions for the appearance of ISIS.
The US doesn't need to bomb civilians to murder them, they already murder half a million civilians worldwide every single year through economic sanctions, in which Iran is plastered.
From the Wikipedia article of Atrocity Propaganda (I added emphasis):
Atrocity propaganda is the spreading of information about the crimes committed by an enemy, which can be factual, but often includes or features deliberate fabrications or exaggerations. This can involve photographs, videos, illustrations, interviews, and other forms of information presentation or reporting
"The inherently violent nature of war means that exaggeration and invention of atrocities often becomes the main staple of propaganda. Patriotism is often not enough to make people hate the enemy, and propaganda is also necessary"
The application of atrocity propaganda is not limited to times of conflict but can be implemented to sway public opinion and create a casus belli to declare war
Most people polled in most eastern Europe post-Soviet countries who lived in socialism (except a few like Poland or Estonia) claim that life was better under socialism. Hard to blame them, I can't imagine how safe and free from anxiety I'd feel if I had a guaranteed job, housing costed 3% of my monthly income, and my neighborhood was walkable and full of affordable canteens with cheap seasonal ready meals. Sure, it would be a small flat, I wouldn't own a car, and I'd have to wait 4 years on a list to buy a new radio, but those are literally non-issues to me in comparison.
See, I think capitalism can work, we just need way more controls
But that's literally the problem right there. We don't lack control because there isn't enough scientific knowledge or because the people naturally oppose this control. We don't and we won't have control because the capitalists, who happen to be in power, profit more from fossil fuels whose supply they can control than from renewables which are endless and affordable.
If you want an example of somewhere where there is this control, I can point you towards China, the manufacturer of some 95% of the world's supply of photovoltaic modules and the spearhead of electrification. In China it's not capitalists in power, it's the people through their communist party, and this results in, well, actual policy.
Your comment, to me, reads like "we don't need to abolish absolutist monarchy, we just need controls on the rights of the serfs". Like, it's literally the system preventing these controls, and once abolished, the problems sort themselves out rather automatically.
I am not sure how another economic system will fix this
You answer yourself shortly afterwards
The issue is getting this done politically
Under socialism, since there are no private owners of companies or oil, there is no incentive for them to lobby the policy in their favour. If you want evidence for this, I could pinpoint you to the People's Republic of China manufacturing some 95% of the world's supply of photovoltaic modules (already the cheapest form of energy available to humanity), spearheading electrification with Ultra-High-Voltage electric transmission lines and battery technology and supply, and leading the current generation of nuclear reactors. In contrast, my capitalist homeland of Spain had a "tax to the sun" during the previous decade that destroyed whatever solar industry we had, because in Spain the fossil fuel lobbyists do have the power to dictate policy, as opposed to China's socialist system.
Maybe if all of the renewable sector pooled together
We don't need to wait for private companies to collude, though, the socialist policy of the Peoples Republic of China has made it so that 95%ish of solar panels are manufactured in that country, we just need to follow the Chinese example.
I have thing or skill. You want things or skill. Depending how many people want thing or skill, I get paid fairly for it
This is famously not how capitalism works. What you're describing is primitive manufacture as it happened in medieval workshops: a class of tradespeople who owned their tools and their workshop and sold the fruits of their own labour by themselves.
Capitalism works differently because the people with the skills don't own the tools or the workshop, the workshops and tools are owned by people who happen to have generational wealth, called the capitalist class. These people don't have skills, they have money, and with this money they acquire means of producing things, like factories. Then, the skilled workers who don't have the money to buy such factories, enter into "free and voluntary" contracts (not so free or voluntary when unemployment exists) in which they get paid not according to how much they produce, but according to how much they can manage to scrape from the capitalist owner, which always gets a profit from the labour of said people.
This has been well-understood for 200 years since the first formal definitions of capitalism appeared, what you're describing is 13th century primitive capitalism
Yes, let's listen to people living in the US constantly under US propaganda apparatus who won't suffer the consequence of invasion instead of, you know, actual Iranians living in the country
Oh no, a MARXIST voice from Iraq who actually lives in the country??? Damn, guess we should totally listen instead to emigrées like you who left the country 20 years ago and have been exposed to 20 years of USA propaganda!
Or should we listen to Ahmed Al Basheer, who streams from literal German state TV (Deutsche Welle)? Surely entirely apolitical and not at all exclusively funding journalists who geopolitically align with them! Not at all media stations endlessly defending the genocide of Palestinians in Israel! The fact that you claim that "the voice of Iraqis" comes from German state TV tells me enough.
Go ahead: if I've misrepresented your positions, tell me, is Israel engaging committing genocide against Palestinians? Should the current state of Israel be eliminated and the lands of Palestinians returned to their rightful owners?
My entire point is that you're dedicating your online time to create what amounts to propaganda for American invasion of Iran. How many comments have you dedicated to the 300 million participants in past week's strike in India?
You're not commenting about Iran protests because you personally care about Iranians, you're commenting about Iran protests because the US + Israel media apparatus have made this international news and keep protests with hundreds of millions of participants entirely silenced. This is not a coincidence: it's an effort to create bad feelings about the Iranian government through atrocity propaganda to justify the impending invasion, and replicating this propaganda with this timing is essentially running for Israel and the US.
The best way to support Iranians would be to mass-protest against the US-imposed economic sanctions demolishing their economy. US economic sanctions murder half a million people yearly, per latest medical studies.
