Gradually getting rid of the bomb

Obama’s done some good this weekend. Yglesias:

The numbers announced Monday, Mr. Cirincione notes, amount to a 30 percent reduction in the nuclear arsenals of the two countries that possess 95 percent of the world’s nuclear weapons.”

In other words, that’s a roughly 28 percent reduction in the total number of nuclear weapons in the world. It’s also a powerful signal to the French, British, and especially Chinese that the United States and Russia are serious about reducing arsenals and that the Obama administration really wants to pursue a nuclear-free world. The fact that the US and Russia contain such a large proportion of global nukes is, after all, a bit of an anachronism as in pretty much all other respects China has clearly replaced Russia as the number two geopolitical player and in some domains the European Union has set itself up as a more-or-less independent great power. It would be very plausible for the Chinese (and much less plausible, though still possible, for the Europeans) to decide they need to react to this situation by “leveling up” and building their own arsenal of thousands of nuclear weapons.

Steps that give the Chinese confidence that they don’t need to do that, that the US and Russia are prepared to level down, will do an enormous amount to help build a more peaceful, more secure world. Not only in terms of the US-China relationship, but also in terms of India’s thinking about its nuclear needs and therefore Pakistan’s thinking and therefore the general problem of proliferation around the world. These reductions, if they come to pass, will be a huge deal.

How important is the MLB All-Star game?

Depends on who you are. For the Dodgers, it’s worth 4 to 5 times(!!) more than a current regular season game. Sky Andrecheck crunches the numbers:

I calculated that the Dodgers have a 39.0923% chance of advancing to the World Series. After a regular season win, this chance increased to 39.2781%, while after a regular season loss, this chance decreased to 38.8368%. On average, this resulted in a change of 0.215% in probability to advance to the World Series and hence, a 0.108% change in probability of winning the World Series (0.215% times 50%). Thus, a regular season game is worth about 0.108% in championship probability to the Dodgers (only about 39% as important as an average game). An All-Star win however, will increase their chances of winning the World Series from 19.5462% (39.0923*.5) to 20.0387% (39.0923*.5126), a difference of 0.4925%. Comparing this mark to the .108% for the regular season game and we find that the All-Star game is not only worth more than a regular season game to Los Angeles, it is worth vastly more than than a regular season game. In fact, the All-Star game is worth somewhere on the order of 4 to 5 times more than a current regular season Dodgers game.

A fuss was made over Chad Billingsley bowling over the catcher during a Dodgers-Padres game this past weekend. Would Billingsley have done so at the All-Star game? Likely not. But this analysis shows that if there is one game the rest of the season in which LA players should sacrifice life and limb, it is Tuesday night’s “exhibition” contest.
