14 greatest engineering challenges of the 21st century

It's yield is quite low... more of a big kaboom rather than a small nuke.

Given the latest advancements in technology, a sub-kiloton nuke could be fit inside a briefcase, but "the terrorists" (and 90% of the world) doesn't have that capability.

A big kaboom still sucks and I don't think anyone would be very consoled by that fact.

I thought you liked to refer to them as 'the terrorists.'

Honestly, can you tell me where a terrorist would acquire such an extremely high tech piece of weaponry? Have we ever made or seen one ourselves? Who in the world do we know who could make such a thing? Briefcase nukes are not a concern.

See 'remote possibility.'

I am all for intergrating the gene from the cochroach that can survive radiation into our genetic code.

are all former soviet nuke heads accounted for ? NO
where are they ? God only knows , and those who have it , or may be even they dont know it !!

drugs are sneaked in every day of the week , also how can u be sure that the iranian ambassador will not sneak in the first small iranian nuke through a "diplomatic bag" or whatever its called , and then Washington Kaboom !! , and u will never be able to prove how it came in , you would not even have an inclination how it happened!!

Tell me again , who reports to you on the latest most secretive nuclear technology the whole world reached ?!!

Russian Claims Chechens Have Nuclear Device

There isn't much detail there. Also it claims that the weapon cannot be detonated.

Again, the yield of such a weapon and its difficulty to procure, activate and use make it a less desirable choice for actual usage, then it is to say "OOOOH! LOOK! WE HAS A NUKE!" I'm sure it's total output upon detonation doesn't hit half a kiloton.

Davey's output was usually 10 to 20 tons. Hardly true "nuke power". There's a steep cliff of diminishing returns when you miniaturize a nuclear weapon... a point where you don't get enough bang for your buck, excuse the pun. Of course, when people hear the word "nuke", they automatically think of the mushroom cloud making 20 megaton multiple warhead harbingers of death that couldn't fit on the back of a truck, much less in a suitcase.

Granted , still what am trying to say is that there are small size nukes ( not neccessarily hand bag size but still small and easy to smuggle) secondly its not about how much detonation power it has , but about being able to actually smugle and activate a nuclear device inside the US , even if its explosive power is as big as a firecracker , those technical difficulties they mentioned were a few years ago , no body knows what happened since then!!
