Here is one good bit of many:
I think that there are two big dangers from a Trump administration: one is a crisis, either the collapse of NATO or starting a nuclear war with another state, and the other is that he does a “grand bargain”, particularly because things probably won’t go very well for him at home and he will need a foreign policy success: he has an early summit with Putin and comes out with some kind of showy deal, which is very bad for the security of frontline states. So yes, I am worried about that. Putin can offer Trump cooperation on terrorism; he can offer cooperation on Syria. I think both of those are essentially nugatory, and if there was any real willingness to cooperate, they would be cooperating already, so you don’t need a grand bargain to have cooperation on that. But he can offer it; he can also offer some kind of deal on the front line: for example, taking missiles out of Kaliningrad in exchange for America cancelling its missile defence programmes, and possibly also going even further: Russia pulling troops back from its western military district and America pulling its forces out of the frontline. I think that would be absolutely catastrophic. So there are different levels of importance in this grand bargain, any of them bad.
Here is the whole interview.
