A hand grenade could have the power of a small nuclear weapon, depends on how small you get.
Actually no. A 'nuclear weapon' requires a minimum amount of radioactive material to produce fission. Subcritical masses of such material will not produce a chain reaction - there is no nuclear reaction, so they are not 'nuclear' weapons.
A 'dirty bomb' may contain radioactive material, but that doesn't make them nuclear weapons any more than the glow-in-the-dark paint on the hands of your wristwatch makes it a nuclear clock.
On thread - 'weapons of mass destruction' is a term that literally refers to the purpose to which a particular weapon is put, not it's provenance. One can cause mass destruction with a BB gun given enough time and determination.
This interpretation from effects applies even more to terrorism - the Beltway Sniper certainly caused terror, armed with no more than a hunting rifle. (Although that doesn't necessarily make him a terrorist - just because the god that told him to do it was Allah, it doesn't make him any different from other garden-variety gun-nut serial killers). The 'randomness' seems to be the biggest factor in causing terror, but has nothing to do with the relative mass of the destruction it causes.
However, usage suggests that WMD refers only to Nuclear, Biological and Chemical weapons, or (most recently) just biological and chemical ones ( since most commentators (and actors) prefer to refer specifically and separately to nuclear weapons).
So on both these grounds, the new bomb cannot really be called a WMD. It's terrorist potential depends on just how accurate the sattelite guidance system is.
If it can obliterate the Iraqi chemical weapons bunker next door without so much as rattling the windows of my house, then it is a precision instrument. If, on the other hand, it accidentally lands on the Chinese Embassy, or a detachment of British or Australian troops, it makes the American military look like either terrorists or incompetants, or both.
