If Russia drops a bomb, then NATO immediately deploys conventional bombs with their own air force on all Russian forces in Ukraine, and China/India both sanction Russia (which basically means the whole world is sanctioning Russia, since nobody will want to piss off the USA and EU and China and India - even NK might sanction Russia).
In other words, if Moscow drops a nuke then their military and their economy both disintegrate.
The automobile - pronounce it out loud, you’ll say it something like “ow-toe moh-beel”, i.e. in a German accent. Because Germans invented cars.
The assault rifle. They invented the concept, a handful of prototypes without the relevant doctrine (or for the 1890s one, even a detachable magazine) is irrelevant. Fight me, @bluewing.
