SIPRI has estimates of nuclear arsenals out. Their estimate of Israel's arsenal makes way more sense than the common view.
The nuclear powers have the following arsenals:
Russia: 8,500 warheads.
America: 7,700.
China: 250.
France: 300.
Britain: 225.
India: 90-110.
Pakistan: 100-120.
Israel: 80.
North Korea: Up to 8.
The Israel estimate is of most interest given that I've doubted all those references to Israel having two or three hundred large warheads.
Maybe next year Iran gets on the list, eh? That would be swell.
