Is this true? Nobody has a counter to ICBMs as far as I know.

Defending against strategic bombers is a different game from submarine-launched cruise missiles / hypersonics too. If you don’t spot the submarine 50 miles off your coast you can’t defend against the hypersonic. Whereas you apply a completely different set of detection and response systems for long-range bombers.

Sure the net intention of these capabilities may the same, but we are talking about whether there are counters to these weapon systems.
