I think that Chris Hayes is correct.
Israel and Saudi do have a strategic problem named “Iran”. And, while I am no expert in the domestic politics of either country, I suspect that probably the current leadership in both countries feel that they benefit from having an enemy. Nor is Iran an angel.
However, the US bumbling into a war with a country the size of Alaska; and with a population of 80 million; that is thousands of miles away from us; And doing so without any major allies; Is just fricking plain stupid.
Domestically, I assume the plan is to have a Bush 43 style war in order to boost the Republican chances at the elections.
