It’s been said for every evolution in military hardware, but could this actually make war impossible (if both sides have them)?

What could you do short of nuclear strikes to get past a wall of lasers taking out all of your missiles and vehicles?

And it’s so cheap to fire them, how could you come up with something that could beat it before you ran out of money?

And how long before we do have MW lasers powerful enough to take out a nuclear RV? Maybe then tungsten rods from orbit finally make sense? But you could probably just destroy the satellite from the ground at that point.
