They can only reach that speed during boost (3-5 mins) and reentry (2 mins). The remainder of the time (25 mins or so of suborbital flight) is very detectable.

The issue with hypersonic weapons is that they can fly low enough to be undetectable, and fast enough to reach their target before anyone knows what happened. That's enough to make any nation feel insecure and vulnerable and trigger happy.
