Or just use impact or explosions to destroy the missiles. Or if you want to use lasers you use very short intense bursts, assuming you can generate such bursts. Countermeasures make things more difficult, but they aren't the end of everything. You get counter counter measures and so on. Tim

You might look at the latest IEEE Spectrum magazine. The cover article Off Target is on space weapons. A good read. Some points from it are: A layer of titanium oxide powder could reflect 99.9% of incident laser energy (for missle bodies) For ground structures, a pool of dyed water about 3cm deep on the flat roof of a two-car garage would provide protection against 100 seconds of a 20MW laser. The laser is burning 500Kg/s of hydrogen/flourine for a total of 50tons for 100 seconds. Smoke or water vapor are also good defenses.
