The Iran war was one of the biggest economic boons Russia could hope for; the disruption of oil and gas exports from Middle East with the associated spike in global prices brought Russian economy back from the dead, as now their exports are so much more valuable.

It's not the first time I see comments similar to this and I honestly can't even begin to grasp how anyone can think that the US is in any way shape or form at risk from Iran.

If it spends enough to trigger the debt bomb literally pounding sand, that could do it. It isn't Iran that is the danger though. The US could just walk away any time and be fine.

And leave their “partners” to clean up the mess?

I'm sure people said the same about the USSR invading Afghanistan.

The US right now cannot keep its bridges from collapsing. It cannot keep its children safe from men with guns. It cannot keep its citizens fed or housed. It is failing to provide adequate healthcare for a majority of its population, it cannot even keep its children vaccinated against measles. Our science agencies are being run by crackpots. Our mass media is being combined under one single owner.

This doesn't even consider the impending existential challenges of climate change.

And this nation, instead of fixing its crumbling domestic infrastructure - educational systems, health care systems, or anything that would benefit the citizens of the US - has chosen to launch an attack against a foreign nation that has already cost 10s of billions of dollars and will likely cost vastly more.

All the political and economic capitol that is required to maintain and improve stable conditions is instead being poured into murder in a desert thousands of miles from home.

I'd argue that Vietnam and Al-Qaida/Afghanistan/Iraq where much lesser "risks" than Iran, and those still left lasting scars on US society, self-image and standing.
