Could H-bombs be applied as a kind of "force field" air defense system?

One clear takeaway from the Russo-Ukraine war is that air defense systems don't work very well, at all. The very best, multi-billion dollar air defense systems have proved virtually worthless in Ukraine. Now, I know that Israel claims their "Iron Dome" has a 90% success rate. But, remember, Israel is a very tiny country, and the Palestinians have little more than toy, pop-gun rockets to attack it with. Iron Dome wouldn't be any more successful than any other system in Ukraine, or any genuine, competitive air defense context. So, we are faced with a situation where not only Russia and China, but North Korea, Iran and Pakistan could potentially annihilate much of the U.S. with nuclear weapons atop missiles or drones of various types. So, what could be done to rectify this situation? Well, desperate times call for desperate measures. What is the most powerful energy source, by far, known to man? The H-bomb. It's so powerful that, in the U.S., no one is allowed to possess more than about 3 pounds of Uranium ore, even though Uranium ore is, itself, relatively harmless. It's so powerful that we've largely suppressed the development of nuclear technology since the 1950's. It may be, that that needs to change, if we wish to remain safe from nuclear attack from "rogue" nations. One thing we know, for sure, one H-bomb detonation will clear out 1000 cubic miles of air space absolutely, and totally . No need for targeting, no possibility of missing -- all incoming missiles gone, all nuclear warheads vaporized without any possibilty of their mechanisms proceeding to nuclear detonation. Isn't that beautiful, and incredibly simple? Now, I realize radiation is a concern, even from a defensive weapon detonated in space, or over the oceans. However, couldn't H-bombs be developed specifically to minimize radioactive fallout, for such defensive purposes? Isn't this worth pursuing, under these particular circumstances?
