> For one, the countries you labelled as problematic aren't the only ones on the list, so the $3b is vastly understated.

I've addressed this. The absolute value is neither here nor there. What matters is how much is exported to problematic regimes. The vast majority of the remaining exports are to countries like Japan, Norway, Ukraine, UK, Australia, Poland... . These countries by and large use the weapons for legitimate defense purposes. Perhaps you can find another billion by adding in the UAE and Bahrain, and a couple of others but by the time you get down to Thailand it's comparatively peanuts per country.

> Russia would currently pay a premium, so Iran selling $1.8b would translate to what at market rates?

Perhaps. Who knows? Happy to look at any further data on this that you can pull out. Even if it's significantly less, we're talking about a single shipment of drones to one country. Iran's overal arms exports will be dramatically greater than this, and includes other exports to Russia as well as exports to problematic regimes or organisations like North Korea, Sudan, Hamas and Houthi rebels.

> The US has propped up and supported extremist regimes for over a century, something neither China nor Russia nor any other country can claim.

This is a tricky comparison since China and Russia haven't existed in their current form for a century. But look, China and Russia are extremist regimes. They oppress minorities, brutally shut down protests, tightly control media and the internet, have cults of personality, conduct sham elections, etc... . The Soviets have been supporting extremist regimes in other countries for virtually a century - look at Afghanistan, Cuba, Angola, Mozambique, and the Congo. And as I said in my post, Russia is right now explicitly propping up Belarus, Chechnya, Moldova and many more. China's activity in the Korean war allowed the formation of North Korea and China continues to be one of the few countries that supports it through political and economic backing. Let me repeat this for clarity: North Korea, arguably the most oppressive regime in existence, would not be able to exist if it were not for the support of countries like China and Iran.

> Of the Allied forces, the US went into war the latest (only after Japan and Germany declared war on the US) and gave generous amnesty to some of the worst murders from both Nazi Germany and Japan.

> No other country on earth can claim anything like this.

China is prosecuting ethnic cleansing of its Uyghur population, including forced sterilisation and labour and other abuses. Several organisations and nation states regard this as a genocide. It's going on right now. It also killed 15-55 million of its own people by implementing the "Great Leap Forward" in 1958-62. The Soviet Union caused a man-made famine in Ukraine that killed around 4 million people. Do you think any of the perpretators of either of those have gotten just retribution to this day? Forget about amnesty - their governments have actively supported these acts.

> Please don't minimise the crimes of the US by trying to compare them to other countries

Putting in context is not minimising. I maintain that the US is far from alone in the scale of its unethical behaviour, and nothing you've said is compelling otherwise.
