Do not think Trump asked for this otherwise he would have taken credit in early morning tweet very next day and given multiple news conferences. This looks like totally UK based action without taking US into account and no reason to take EU into account.So if the EU weren't going to do anything/couldn't do anything why did we have to. If it was to help America why ? why always us. Everyone else seems to get along fine without bending over backwards to help them.
Maybe was a strategy to take focus away from Brexit, looks like it has backfired badly.
