the thing is, people with Western-type views (America, Europe, NATO-allies, others) never actually want to use these horrific weapons and choose to leave them in the background as the unspoken deterrant, while these north korean clowns, and the nutty tinpot arab dictators like aberdinajhad, parade them out, brag and boast about them, and given half a chance would actually USE them directly or through their terrorist-puppet stooges, like hezbolloh and al-quaeda. when was the last time you heard the USA actually talking about their nuclear weapons and programs, much less even acknowledging said weapons deployed or actively in use? the USA does not discuss these programs, and Israel is even more secretive, as they have had the capability probably since the 1960s and still deny their existence to this very day. there is a huge difference in the views of these weapons, between the West, and the nutbags currently joining the nuclear club.
President Ahmadinejad is the head of a Persian country, not Arab. The common belief is that France sold one of their warheads to Israel during the Cold War when Israel was fighting their Arab wars. Any truth behind this is still yet to be discovered I guess. The US, or most nuclear armed country for that matter, have absolutely no intention of using these weapons for fear of global retaliation. Virtually every ally will cease to be one should a country use a nuclear warhead offensively; even if it is a pre-emptive strike. The concept of MAD still exists to this very day. This is why most wars fought by the larger nations are fought conventionally with the use of boots. Tactics nowadays use precision rather than destruction to achieve military goals so long as collateral and friendly damage is minimized. Although the exception would be the stupid drone strikes that Obama keeps ordering.
