The KGB/GRU PoV is unwelcome as always.
Iran, like Russia, is a thug-pariah. Nobody trusts them. Nobody likes them. They can only buy cooperation.
With their funds cutoff they’re done.
Sink their navy, bomb their oil terminals, blow up their pipelines, intercept their missile retaliation, blockade gulf of Aiden then let them wither on the vine for lack of supplies and funding.
Iran is an ally of Russia & China, neither of whom will leave Iran withering on the vine. On the contrary they will provide Iran with military assistance. While the US has oil and gas to sustain us in an emergency, most of Europe doesn’t and their economies would go into a severe depression if Mideast oil was cut off. While we need to retaliate against Iran, it would just be another neocon folly to start a full scale war with them.
Keep in mind Iran most likely already has agents embedded in the US that came up through our southern border and are ready to commit terrorism the moment we attack Iran. Biden has put us in a bad position.
