I am thinking that at least part of the reason that senators John McCain and Lindsay Graham folded on Rex Tillerson is that without Tillerson there is no State Department presence in the White House. Foreign policy would be controlled by ultra-nationaliist Stephen Bannon, who wrote Trump’s extremist inauguration address, and National Security Adviser Mike Flynn, who is under investigation for his contacts with Russia and whom much of the intelligence community (both in the US and internationally) assume is a Russian intelligence asset. Keep in mind that both McCain and Graham, as senators, have been briefed on the investigation into Flynn and know much, much more than either the press or public. The notion that they have to approve a nominee for secretary of state who is also close to Vladimir Putin must turn their stomachs, but intelligence probably shows that, unlike Flynn, there is no evidence that Tillerson is actively colluding with the Russian government. And Tillerson, at least, judging by his answers to the senators during his hearing, might provide a moderating hand. Right now we look to a general named Mad Dog Mattis, as secretary of defense, to be the sole moderating force in the Trump administration’s foreign policy.
