The Iranian attack today on the US military infrastructure in Bahrain is much more serious than the one a few days ago that included two downed UAVs.
At least 4 cruise missiles and 9 drones that AHD-131/136 have launched so far, aimed at at least two places in Bahrain.
Iran appears to have run out of patience with repeated US violations of the memorandum of understanding, with US airstrikes targeting southern Iran on several nights over the past week. Iran understands that they still have a lot of room for escalation - an escalation that currently does not favor the US, and they know that the resumption of full-scale war will come sooner or later.
The US and its Gulf allies continue to suffer from a critical shortage of interceptors, while the US at home continues to suffer from its own critical lack of support in a forever inconclusive war in the middle of the world.
