You can't put the toothpaste back in the tube. This is mindless peacenick pandering, there's no "ambition" anywhere in it... Unless he takes it to the level of "us first" then it's ambition, and annihilation.
Noble though the thought might be.
Say what you want, but cutting back on teh excessive arsenal of nuclear weaponry would reduce the number of missiles pointed around the world, and would also reduce military budgets by tens and maybe hundreds of billions each year, and free up a lot of personnel for other duties. Not this year, but when a drawdown commences. We have so many nukes, we could reduce by half and still outnumber the rest of the wordl.
Trick is, do the reduction so that no terrorists or blackmarketeers get their hands on any fissionable or radioactive material.
THAT is the real danger.
Nuclear weapons are not covered under the 2nd Amendment. Reducing their numbers will not reduce anyone's security. They keep nobody safe.
We can accomplish more with one bullet to Kim Jong Il's head and each of his whacked out subordinates than we can with a trillon dollars in nukes.
Until that day, we will keep subs off the coast of Korea, in the Sea of Japan ready to launch Seals or missiles.
