The USA is a brutal dictatorship who invaded a sovereign country. What's the difference exactly? The USA has invaded someone more recently than Russia has, and they do it a lot more often. They're also more dictatorial and more brutal. The fact that the USA is mad at Iran for supporting their enemy is completely understandable. They're not being hypocrites, it's just mafia tactics and they're not ashamed of it. What's not understandable is you or anyone saying USA sending weapons to Ukraine and Iran sending weapons to Russia are somehow not equivalent.

To be clear, I am not at all justifying or forgiving the use of sanctions, it's a barbaric form of warfare that explicitly targets non-combatants, the USA should be ashamed and their leadership jailed.
