At TFL, we're making journeys safer for everyone, and that includes improving safety on London's roads.

That's why we and London boroughs are lowering more speed limits to 20 miles per hour,

because 20 miles per hour roads have already reduced collisions resulting in deaths or

serious injuries by 24%. That is how we're making journeys in London safer and brighter for everyone.

Such TFL Improvement Plan to the Mayor of London and TFL every journey matters.

This is CBS Eye in the World I'm John Batchy with my colleague Henry Sikowski of the

Nonproliferation Policy Education Center. A new issue to me, Henry, what is

forward deployment of nuclear sharing? What is it that there was terms of art referring to?

They have to do with the practice that began in the mid-50s, roughly,

when the United States did not have long-range bombers, much less intercontinental ballistic

missiles, and could not reach or deal with the Russian military formations that we thought

were quite large, that we would have to target with nuclear explosives since we didn't have

enough conventional forces to stop them. The decision was made, well, let's move our nuclear

warheads onto NATO or Western European soil so that they could be on the ready if the Russians ever

invade. It also was a condition militarily, technically, at that time, that we had a very

difficult time aiming our weapons. We did not have precision-guided munitions, and when you have

a large mass of military formations coming at you, the thought was, well, we have to use

pretty large explosives since we can't aim, and nuclear weapons seem to be the answer to that problem.

Now, that sort of military technical conditions lacking long-range reposition have all gone away.

It's been 70-some odd years, that a lot has happened in military science, but we still have the

weapons in Western Europe and Belgium, Germany, Italy, Great Britain, and France, of course,

had nuclear weapons with their own. They're in Turkey. I may have gotten one or two countries
