Russia's Putin reveals 'invincible' nuclear weapons
Couple of questions for anyone who knows about this kind of hardware.<p>(1) Is the nuclear arms &quot;race&quot; still on? Ie, Is the US still playing a game of my offence&#x2F;defence is better than yours with The States?<p>(2) does this count as a new bar or milestone or somesuch, and if so when was the last &quot;milestone.&quot; Ie, something that changes the strategic dynamic between major powers in a somewhat meaningful way.
