The latest, and now deadly, attacks on US positions in Middle East are likely to lead to an unavoidable refocusing of US (and UK) attention to Ukraine's detriment. Convenient for Russia.
Hard to believe US has the appetite to fully engage Iran. More likely, under Trump at least, would be greater withdrawal from Middle East - can't attack what's not there.
The US is blaming 'Iran backed militia groups operating in Iraq and Syria'.
So Iran is getting specifically fingered for this? Iran is now a legitimate target as they provided the weapons and funding?
Where does that leave Russia? Many thousands have been killed by US backed folk operating in Ukraine. The logic that says Iran is a legitimate target following this attack also suggests the US (and UK) is legitimate target for Russia. Does the US and UK administrations accept that they are legitimate Russian targets?
