We have no missiles designed to hit anything beyond the threat we face from India, that's a necessary part of our deterrence and all of our focus is dedicated to that end. We have no ICBM, nor do we need one. Especially not for the US.
Yes we have uneasy relations with the US, but we're not enemies. We've never been at war with them and probably never will be. And even if the situation was worse, what would an ICBM change?
The US' greatest offensive tools for jumped-up pipsqueak nations who've acquired nukes isn't war, it's sanctions, economic damage, diplomatic and political damage at every level. They can do us harm without firing a single bullet, what's more, far from an ICBM changing that, it would only add further justification for taking such action against Pakistan. Right now, most of the world is not against us in the way the Trump administration is, what members are asking for would be sure to change that.
North Korea's diplomatic strategy is certainly a bad one for us to follow.
