Several newspapers and news sites have covered the release, in Pakistan, of a US-Canadian couple, Caitlan Coleman and Joshua Boyle. They had been kidnapped in Afghanistan in October 2012, and had three children whilst being held by the Haqqani Network.
Significant in this is the tone of the US government statement. This certainly seems to refer to other Americans (and other westerners?) in a similar predicament, but also that the US government has pretty clearly expectations of Pakistan to address this.
It may be too early to talk of a 'Trump Doctrine' but at least part of what we see forming is a desire for other countries to take on duties and responsibilities, with no doubt some behind the scenes encouragment from either carrot or stick. There is little doubt here, that Pakistan was held responsible either for the kidnapping itself, or its continuation.
The times they are a changing?
