>Many around the world would consider the USA worse in this regard than iran

Many people think many things, many of them are wrong. What do you think?

I think that those many are mostly correct. The US has funded those it knows will sign contracts with US companies to purchase arms (mostly, construction and oil deals also). They may even prove to be correct in the Iran situation too. Time will tell.

I think being able to trade and move is good and builds cultural bridges which assists demilitarisation
