US can huff and puff BUT there is not much it can do. Pakistan export to US is not that much and can easily be redirected somewhere else. EU had not been in line with US policy lately and EU really does not have any beef with Pakistan. In fact EU position is more in line with Pakistani one - try find an inclusive political solution. Whereas, US is goal is to intensify war that they are loosing and TRY to disrupt the Eurasian geo political plot that they completely lost.Support for the Taliban, if proven, is enough for sanctions.
Actually it is enough that US/EU decides that they do not like the colour of your moustache,
