You will recall that Mitt Romney identified Russia as a significant threat to the US during the 2012 debates, and was brushed off by Obama, who clearly viewed the Russians solely as a regional power with strategically useless nuclear weapons. Romney wasn’t completely right, but he wasn’t completely wrong, either, as events since 2012 have established.
How long ago that seems! Today, a GOP president and his reactionary followers appear to view Russia more as an ally against liberalism and Islamic extremism than an adversary in spite of its aggressive actions in Ukraine and Syria. On the other hand, the GOP foreign policy establishment still sees Russia as a major threat. As a result, with the departure of Bannon, Trump is essentially isolated within his own administration on this point. The hiring of Bolton will make this situation worse, not better.
Where is this ultimately going? In the short run, it is hard to tell if Trump can prevail over the rest of his own government. In the long run, the GOP will almost certainly default to its previous position as soon as Trump is out of office. That, of course, assumes that there is a long run.
